Using the interrupt affinity mask for checking locality is not really
working well on architectures which support effective affinity masks.
The affinity mask is either the system wide default or set by user space,
but the architecture can or even must reduce the mask to the effective set,
which means that checking the affinity mask itself does not really tell
about the actual target CPUs.

No driver has any business with the internals of an interrupt
descriptor. Storing a pointer to it just to use yet another helper at the
actual usage site to retrieve the affinity mask is creative at best. Just
because C does not allow encapsulation does not mean that the kernel has no
limits.
Retrieve a pointer to the affinity mask itself and use that. It's still
using an interface which is usually not for random drivers, but definitely
less hideous than the previous hack.

Transmitted packet timestamping accuracy can be improved when using
timestamp from the port, instead of packet CQE creation timestamp, as
it better reflects the actual time of a packet's transmit.
TX port timestamping is supported starting from ConnectX6-DX hardware.
Although at the original completion, only CQE timestamp can be attached,
we are able to get TX port timestamping via an additional completion over
a special CQ associated with the SQ (in addition to the regular CQ).
Driver to ignore the original packet completion timestamp, and report
back the timestamp of the special CQ completion. If the absolute timestamp
diff between the two completions is greater than 1 / 128 second, ignore
the TX port timestamp as it has a jitter which is too big.
No skb will be generate out of the extra completion.
Allocate additional CQ per ptpsq, to receive the TX port timestamp.
Driver to hold an skb FIFO in order to map between transmitted skb to
the two expected completions. When using ptpsq, hold double refcount on
the skb, to gaurantee it will not get released before both completions
arrive.
Expose dedicated counters of the ptp additional CQ and connect it to the
TX health reporter.
This patch improves TX Hardware timestamping offset to be less than 40ns
at a 100Gbps line rate, compared to 600ns before.
With that, making our HW compliant with G.8273.2 class C, and allow Linux
systems to be deployed in the 5G telco edge, where this standard is a
must.

Add napi_id to the xdp_rxq_info structure, and make sure the XDP
socket pick up the napi_id in the Rx path. The napi_id is used to find
the corresponding NAPI structure for socket busy polling.

When eswitch manager is running on ECPF, host PF should be treated
as non eswitch manager port, similar to other VF vports.
Fail to do so, results in firmware treating PF's vport as ECPF
vport for eswitch ACL tables.
Non zero check to figure out if a given vport is other vport or not
is not sufficient becase PF vport number = 0 on ECPF.
Hence, create esw acl tables with an attribute of other vport.

Currently ECPF enables external host PF too early in the initialization
sequence for Ethernet links when ECPF is eswitch manager.
Due to this, when external host PF driver is loaded, host PF's HCA CAP has
inner_ip_version supported by NIC RX flow table.
This capability is later updated by firmware after ECPF driver enables
ENCAP/DECAP as eswitch manager.
This results into a timing race condition, where CREATE_TIR command
fails with a below syndrome on host PF.
mlx5_cmd_check:775:(pid 510): CREATE_TIR(0x900) op_mod(0x0) failed,
status bad parameter(0x3), syndrome (0x562b00)
Hence, enable the external host PF after necessary eswitch and per vport
initialization is completed.
Continue to enable host PF when eswitch manager capability is off for a
ECPF.

These symbols are required by the VDPA implementation to create rules

We do not deal with putting the prototypes in a header file since they
already exist in include/linux/mlx5/fs.h.

All drivers which implement the devlink flash update support, with the
exception of netdevsim, use either request_firmware or
request_firmware_direct to locate the firmware file. Rather than having
each driver do this separately as part of its .flash_update
implementation, perform the request_firmware within net/core/devlink.c
Replace the file_name parameter in the struct devlink_flash_update_params
with a pointer to the fw object.
Use request_firmware rather than request_firmware_direct. Although most
Linux distributions today do not have the fallback mechanism
implemented, only about half the drivers used the _direct request, as
compared to the generic request_firmware. In the event that
a distribution does support the fallback mechanism, the devlink flash
update ought to be able to use it to provide the firmware contents. For
distributions which do not support the fallback userspace mechanism,
there should be essentially no difference between request_firmware and
request_firmware_direct.
