71ad8d55f8 devlink: Replace devlink_port_attrs_set parameters with a struct
Currently, devlink_port_attrs_set accepts a long list of parameters,
that most of them are devlink port's attributes.

Use the devlink_port_attrs struct to replace the relevant parameters.

1da63ddd0e bnxt_en: allow firmware to disable VLAN offloads
Bare-metal use cases require giving firmware and the embedded
application processor control over VLAN offloads. The driver should
not attempt to override or utilize this feature in such scenarios

a196e96bb6 bnxt_en: clean up VLAN feature bit handling
The hardware VLAN offload feature on our NIC does not have separate
knobs for handling customer and service tags on RX. Either offloading
of both must be enabled or both must be disabled. Introduce definitions
for the combined feature set in order to clean up the code and make
this constraint more clear. Technically these features can be separately
enabled on TX, however, since the default is to turn both on, the
combined TX feature set is also introduced for code consistency.

bd3191b5d8 bnxt_en: Implement ethtool -X to set indirection table.
With the new infrastructure in place, we can now support the setting of
the indirection table from ethtool.

When changing channels, in a rare case that firmware cannot reserve the
rings that were promised, we will still try to keep the RSS map and only
revert to default when absolutely necessary.

v4: Revert RSS map to default during ring change only when absolutely
    necessary.

v3: Add warning messages when firmware cannot reserve the requested RX
    rings, and when the RSS table entries have to change to default.

v2: When changing channels, if the RSS table size changes and RSS map
    is non-default, return error.

1667cbf6a4 bnxt_en: Add logical RSS indirection table structure.
The driver currently does not keep track of the logical RSS indirection
table.  The hardware RSS table is set up with standard default ring
distribution when initializing the chip.  This makes it difficult to
support user sepcified indirection table entries.  As a first step, add
the logical table in the main bnxt structure and allocate it according
to chip specific table size.  Add a function that sets up default
RSS distribution based on the number of RX rings.

v4: Use bnxt_get_rxfh_indir_size() for the current RSS table size.

v2: Use kmalloc_array() since we init. all entries afterwards.
    Use ALIGN() to roundup the RSS table size.

c2dec363fe bnxt_en: Fix statistics counters issue during ifdown with older firmware.
On older firmware, the hardware statistics are not cleared when the
driver frees the hardware stats contexts during ifdown.  The driver
expects these stats to be cleared and saves a copy before freeing
the stats contexts.  During the next ifup, the driver will likely
allocate the same hardware stats contexts and this will cause a big
increase in the counters as the old counters are added back to the
saved counters.

We fix it by making an additional firmware call to clear the counters
before freeing the hw stats contexts when the firmware is the older
20.x firmware.

b8056e8434 bnxt_en: Fix accumulation of bp->net_stats_prev.
We have logic to maintain network counters across resets by storing
the counters in bp->net_stats_prev before reset.  But not all resets
will clear the counters.  Certain resets that don't need to change
the number of rings do not clear the counters.  The current logic
accumulates the counters before all resets, causing big jumps in
the counters after some resets, such as ethtool -G.

Fix it by only accumulating the counters during reset if the irq_re_init
parameter is set.  The parameter signifies that all rings and interrupts
will be reset and that means that the counters will also be reset.

7a13240e37 bnxt_en: fix ethtool_reset_flags ABI violations
The ethtool ABI specifies that the reset operation should only clear
the flags that were actually reset. Setting the flags to zero after
a chip reset violates this because it does not include resetting the
application processor complex. Similarly, components that are not yet
defined are also not necessarily being reset.

The fact that chip reset does not cover the AP also means that it is
inappropriate to treat these two components exclusively of one another.
The ABI provides a mechanism to report a failure to reset independent
components via the returned bitmask, so it is also wrong to fail hard
if one of a set of independent resets is not possible.

It is incorrect to rely on the passed by reference flags in bnxt_reset(),
which are being updated as components are reset. The initially requested
value should be used instead so that hard errors do not propagate if any
earlier components could have been reset successfully.

Note, AP and chip resets are global in nature. Dedicated resets are
thus not currently supported.

has work to do, we will handle it when NAPI calls us back.

This is not optimal.  We potentially leave an unproceesed entry in
the NQ.  When we are finally done with NAPI polling and re-enable
interrupt, the remaining entry in the NQ will cause interrupt to
be triggered immediately for no reason.

entries are handled even if the first completion ring has reached

8d85b75b4e bnxt_en: Use pci_get_dsn()
Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().

Use of put_unaligned_le64 should be correct. pci_get_dsn() will perform
two pci_read_config_dword calls. The first dword will be placed in the
first 32 bits of the u64, while the second dword will be placed in the
upper 32 bits of the u64.

On Little Endian systems, the least significant byte comes first, which
will be the least significant byte of the first dword, followed by the
least significant byte of the second dword. Since the _le32 variations
do not perform byte swapping, we will correctly copy the dwords into the
dsn[] array in the same order as before.

On Big Endian systems, the most significant byte of the second dword
will come first. put_unaligned_le64 will perform a CPU_TO_LE64, which
will swap things correctly before copying. This should also end up with
the correct bytes in the dsn[] array.

While at it, fix a small typo in the netdev_info error message when the
DSN cannot be read.

d407302895 bnxt_en: Fix logic that disables Bus Master during firmware reset.
The current logic that calls pci_disable_device() in __bnxt_close_nic()
during firmware reset is flawed.  If firmware is still alive, we're
disabling the device too early, causing some firmware commands to
not reach the firmware.

Fix it by moving the logic to bnxt_reset_close().  If firmware is
in fatal condition, we call pci_disable_device() before we free
any of the rings to prevent DMA corruption of the freed rings.  If
firmware is still alive, we call pci_disable_device() after the
last firmware message has been sent.

12de2eadf8 bnxt_en: Fix RDMA driver failure with SRIOV after firmware reset.
bnxt_ulp_start() needs to be called before SRIOV is re-enabled after
firmware reset.  Re-enabling SRIOV may consume all the resources and
may cause the RDMA driver to fail to get MSIX and other resources.
Fix it by calling bnxt_ulp_start() first before calling
bnxt_reenable_sriov().

We re-arrange the logic so that we call bnxt_ulp_start() and
bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and
bnxt_open().  The former is the normal coordinated firmware reset sequence
and the latter is firmware reset while the function is down.  This new
logic is now more straight forward and will now fix both scenarios.

7e334fc800 bnxt_en: Add missing devlink health reporters for VFs.
The VF driver also needs to create the health reporters since
VFs are also involved in firmware reset and recovery.  Modify
bnxt_dl_register() and bnxt_dl_unregister() so that they can
be called by the VFs to register/unregister devlink.  Only the PF
will register the devlink parameters.  With devlink registered,
we can now create the health reporters on the VFs.

937f188c1f bnxt_en: Fix the logic that creates the health reporters.
Fix the logic to properly check the fw capabilities and create the
devlink health reporters only when needed.  The current code creates
the reporters unconditionally as long as bp->fw_health is valid, and
that's not correct.

Call bnxt_dl_fw_reporters_create() directly from the init and reset
code path instead of from bnxt_dl_register().  This allows the
reporters to be adjusted when capabilities change.  The same
applies to bnxt_dl_fw_reporters_destroy().

0797c10d2d bnxt_en: Remove unnecessary NULL checks for fw_health
After fixing the allocation of bp->fw_health in the previous patch,
the driver will not go through the fw reset and recovery code paths
if bp->fw_health allocation fails.  So we can now remove the
unnecessary NULL checks.

8280b38e01 bnxt_en: Fix bp->fw_health allocation and free logic.
bp->fw_health needs to be allocated for either the firmware initiated
reset feature or the driver initiated error recovery feature.  The
current code is not allocating bp->fw_health for all the necessary cases.
This patch corrects the logic to allocate bp->fw_health correctly when
needed.  If allocation fails, we clear the feature flags.

We also add the the missing kfree(bp->fw_health) when the driver is
unloaded.  If we get an async reset message from the firmware, we also
need to make sure that we have a valid bp->fw_health before proceeding.

325f85f37e bnxt_en: Free context memory in the open path if firmware has been reset.
This will trigger new context memory to be rediscovered and allocated
during the re-probe process after a firmware reset.  Without this, the

0c722ec0a2 bnxt_en: Fix MSIX request logic for RDMA driver.
The logic needs to check both bp->total_irqs and the reserved IRQs in
hw_resc->resv_irqs if applicable and see if both are enough to cover
the L2 and RDMA requested vectors.  The current code is only checking
bp->total_irqs and can fail in some code paths, such as the TX timeout
code path with the RDMA driver requesting vectors after recovery.  In
this code path, we have not reserved enough MSIX resources for the
RDMA driver yet.

The main changes are:

1) Addition of BPF trampoline which works as a bridge between kernel functions,
   BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
   BPF programs for tracing with practically zero overhead to call into BPF (as
   opposed to k[ret]probes) and ii) attachment of the former to networking related
   programs to see input/output of networking programs (covering xdpdump use case),
   from Alexei Starovoitov.

2) BPF array map mmap support and use in libbpf for global data maps; also a big
   batch of libbpf improvements, among others, support for reading bitfields in a
   relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.

3) Extend s390x JIT with usage of relative long jumps and loads in order to lift
   the current 64/512k size limits on JITed BPF programs there, from Ilya Leoshkevich.

4) Add BPF audit support and emit messages upon successful prog load and unload in
   order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.

5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
   (XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.

6) Several follow-up bug fixes for libbpf's auto-pinning code and a new API
   call named bpf_get_link_xdp_info() for retrieving the full set of prog
   IDs attached to XDP, from Toke Høiland-Jørgensen.

7) Add BTF support for array of int, array of struct and multidimensional arrays
   and enable it for skb->cb[] access in kfree_skb test, from Martin KaFai Lau.

8) Fix AF_XDP by using the correct number of channels from ethtool, from Luigi Rizzo.

9) Two fixes for BPF selftest to get rid of a hang in test_tc_tunnel and to avoid
   xdping to be run as standalone, from Jiri Benc.

10) Various BPF selftest fixes when run with latest LLVM trunk, from Yonghong Song.

11) Fix a memory leak in BPF fentry test run data, from Colin Ian King.

12) Various smaller misc cleanups and improvements mostly all over BPF selftests and
    samples, from Daniel T. Lee, Andre Guedes, Anders Roxell, Mao Wenan, Yue Haibing.

We call bnxt_ulp_stop() to notify the RDMA driver that some error or
imminent reset is about to happen.  After that we always call
some variants of bnxt_close().

In the next patch, we will integrate the recently added error
recovery with the RDMA driver.  In response to ulp_stop, the
RDMA driver may free MSIX vectors and that will also trigger
bnxt_close().  To avoid bnxt_close() from being called twice,
we set a new flag after ulp_stop is called.  If the RDMA driver
frees MSIX vectors while the new flag is set, we will not call
bnxt_close(), knowing that it will happen in due course.

With this change, we must make sure that the bnxt_close() call
after ulp_stop will reset IRQ.  Modify bnxt_reset_task()
accordingly if we call ulp_stop.

The decap (VXLAN tunnel) flow rules are not getting offloaded with
upstream kernel. This is because TC block callback infrastructure has
been updated to use indirect callbacks to get offloaded rules from
other higher level devices (such as tunnels), instead of ndo_setup_tc().
Since the decap rules are applied to the tunnel devices (e.g, vxlan_sys),
the driver should register for indirect TC callback with tunnel devices
to get the rules for offloading. This patch updates the driver to
register and process indirect TC block callbacks from VXLAN tunnels.

which can be retrieved using OP-TEE API only, as firmware cannot
access this region directly.

User needs to set the dump flag using following command before
initiating the dump collection:

    $ ethtool -W|--set-dump eth0 N

Where N is "0" for live dump and "1" for crash dump

Command to collect the dump after setting the flag:

    $ ethtool -w eth0 data Filename

v3: Modify set_dump to support even when CONFIG_TEE_BNXT_FW=n.
Also change log message to netdev_info().
