PTP hardware block can be configured to utilize
the external clock. Also the current ptp timestamp
can be captured when external trigger is applied on
a gpio pin. These features are required in scenarios
like connecting a external timing device to the chip
for time synchronization. The timing device provides
the clock and trigger(PPS signal) to the PTP block.
This patch does the following:
1. configures PTP block to use external clock
frequency and timestamp capture on external event.
2. sends PTP_REQ_EXTTS events to kernel ptp phc susbsytem
with captured timestamps
3. aligns PPS edge to adjusted ptp clock in the ptp device
by setting the PPS_THRESH to the reminder of the last
timestamp value captured by external PPS

NIX_AF_TX_LINKX_NORM_CREDIT holds running counter of
tx credits available per link. But, tx credits should be
configured based on MTU config. So MTU change needs tx
credit count update.
An issue exists whereby when both PF & VF are enabled and
PF traffic is flowing, if VF requests for MTU update,
updating the NORM_CREDIT register will lead to corruption
of credit count and subsequent deadlock of tx link as
the NORM_CREDIT register holds running count.
This patch provides workaround by pausing link traffic
using NIX_AF_TL1X_SW_XOFF, waiting for existing packets to

As of now any communication between CGXs PFs and

external switches sending packets back to the
system. This patch adds internal switching support.
Broadcast packet replication is not covered here.
RVU admin function (AF) maintains MAC addresses
of all interfaces in the system. When switching is
enabled, MCAM entries are allocated to install rules
such that packets with DMAC matching any of the
internal interface MAC addresses is punted back
into the system via the loopback channel.
On the receive side the default unicast rules
are modified to not check for ingress channel.
So any packet with matching DMAC irrespective of
which interface it is coming from will be forwarded
to the respective PF/VF interface.
The transmit side rules and default unicast rules
are updated if user changes MAC address of an interface.

Currently, multicast packet filtering is accomplished by installing
MCAM rule that matches all-multicast MAC address and has its
NPC_RX_ACTION set to unicast to PF. Similarly promisc feature is
achieved by installing MCAM rule that matches all the traffic received
by the channel and unicast the packets to PF. This approach only applies
to PF and is not scalable across VFs.
This patch adds support for PF/VF multicast and promisc feature by
reserving NIX_RX_MCE_S entries from the global MCE list allocated
during NIX block initialization. The NIX_RX_MCE_S entries create a
linked list with a flag indicating the end of the list, and each entry
points to a PF_FUNC (either PF or VF). When a packet NPC_RX_ACTION is
set to MCAST, the corresponding NIX_RX_MCE_S list is traversed and the
packet is queued to each PF_FUNC available on the list.
The PF or VF driver adds the multicast/promisc packet match entry and
updates the MCE list with correspondng PF_FUNC. When a PF or VF interface
is disabled, the corresponding NIX_RX_MCE_S entry is removed from the
MCE list and the MCAM entry will be disabled if the list is empty.

NIX uses unique channel numbers to identify the packet sources/sinks
like CGX,LBK and SDP. The channel numbers assigned to each block are
hardwired in CN9xxx silicon.
The fixed channel numbers in CN9xxx are:
0x0 | a << 8 | b - LBK(0..3)_CH(0..63)
0x0 | a << 8 - Reserved
0x700 | a - SDP_CH(0..255)
0x800 | a << 8 | b << 4 | c - CGX(0..7)_LMAC(0..3)_CH(0..15)
All the channels in the above fixed enumerator(with maximum
number of blocks) are not required since some chips
have less number of blocks.
For CN10K silicon the channel numbers need to be programmed by
software in each block with the base channel number and range of
channels. This patch calculates and assigns the channel numbers
to efficiently distribute the channel number range(0-4095) among
all the blocks. The assignment is made based on the actual number of
blocks present and also contiguously leaving no holes.
The channel numbers remaining after the math are used as new CPT
replay channels present in CN10K. Also since channel numbers are
not fixed the transmit channel link number needed by AF consumers
is calculated by AF and sent along with nix_lf_alloc mailbox response.

This patch adds initial support for CN10K's RPM MAC i.e. the driver

Firmware allocates memory regions for PFs and VFs in DRAM.
The PFs memory region is used for AF-PF and PF-VF mailbox.
This mbox facilitates communication between AF-PF and PF-VF.
On CN10K platform:
The DRAM region allocated to PF is enumerated as PF BAR4 memory.
PF BAR4 contains AF-PF mbox region followed by its VFs mbox region.
AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR
PF-VF mailbox base address is configured at
RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its
mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via
BAR2 indirect access.
On CN9XX platform:
Mailbox region in DRAM is divided into two parts AF-PF mbox region and
PF-VF mbox region i.e all PFs mbox region is contiguous similarly all
VFs.
The base address of the AF-PF mbox region is configured at
RVU_AF_PF_BAR4_ADDR.
AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox
size.
The base address of PF-VF mbox region for each PF is configure at
RVU_AF_PF(0..15)_VF_BAR4_ADDR.PF access its mbox region via BAR4 and its
VF mbox regions from RVU_PF_VF_BAR4_ADDR register, whereas VF access its
mbox region via BAR4.

This patch adds support for ndo_set_vf_mac, ndo_set_vf_vlan
and ndo_get_vf_config handlers. The traffic redirection
based on the VF mac address or vlan id is done by installing
MCAM rules. Reserved RX_VTAG_TYPE7 in each NIXLF for VF VLAN
which strips the VLAN tag from ingress VLAN traffic. The NIX PF
allocates two MCAM entries for VF VLAN feature, one used for
ingress VTAG strip and another entry for egress VTAG insertion.
This patch also updates the MAC address in PF installed VF VLAN
rule upon receiving nix_lf_start_rx mbox request for VF since
Administrative Function driver will assign a valid MAC addr
in nix_lf_start_rx function.

This patch modifies the existing nix_vtag_config mailbox message
to allocate and free TX VTAG entries as requested by a NIX PF.
The TX VTAG entries are global resource that shared by all PFs
and each entry specifies the size of VTAG to insert and the VTAG
header data to insert. The mailbox response contains the entry
index which is used by mailbox requester in configuring the
NPC_TX_VTAG_ACTION for any MCAM entry.

Added new mailbox messages to install and delete MCAM rules.
These mailbox messages will be used for adding/deleting ethtool
n-tuple filters by NIX PF. The installed MCAM rules are stored
in a list that will be traversed later to delete the MCAM entries
when the interface is brought down or when PCIe FLR is received.
The delete mailbox supports deleting a single MCAM entry or range
of entries or all the MCAM entries owned by the pcifunc. Each MCAM
entry can be associated with a HW match stat entry if the mailbox
requester wants to check the hit count for debugging.
Modified adding default unicast DMAC match rule using install
flow API. The default unicast DMAC match entry installed by
Administrative Function is saved and can be changed later by the
mailbox user to fit additional fields, or the default MCAM entry
rule action can be used for other flow rules installed later.
Modified rvu_mbox_handler_nix_lf_free mailbox to add a flag to
disable or delete the MCAM entries. The MCAM entries are disabled
when the interface is brought down and deleted in FLR handler.
The disabled MCAM entries will be re-enabled when the interface
is brought up again.

Key Extraction(KEX) profile decides how the packet metadata such as
layer information and selected packet data bytes at each layer are
placed in MCAM search key. This patch reads the configured KEX profile
parameters to find out the bit position and bit mask for each field.
The information is used when programming the MCAM match data by SW
to match a packet flow and take appropriate action on the flow. This
patch also verifies the mandatory fields such as channel and DMAC
are not overwritten by the KEX configuration of other fields.

This patch adds support to verify the channel number sent by
mailbox requester before writing MCAM entry for Ingress packets.
Similarly for Egress packets, verifying the PF_FUNC sent by the
mailbox user.

On 98xx silicon, NPC block has additional
mcam entries, counters and NIX1 interfaces.
Extended set of registers are present for the
new mcam entries and counters.
This patch does the following:
- updates the register accessing macros
to use extended set if present.
- configures the MKEX profile for NIX1 interfaces also.
- updates mcam entry write functions to use assigned
NIX0/1 interfaces for the PF/VF.
