octeontx2-pf: Add TC feature for VFs
This patch adds TC feature for VFs also. When MCAM
rules are allocated for a VF then either TC or ntuple
filters can be used. Below are the commands to use
TC feature for a VF(say lbk0):
devlink dev param set pci/0002:01:00.1 name mcam_count value 16 \
cmode runtime
ethtool -K lbk0 hw-tc-offload on
ifconfig lbk0 up
tc qdisc add dev lbk0 ingress
tc filter add dev lbk0 parent ffff: protocol ip flower skip_sw \
dst_mac 98:03:9b:83:aa:12 action police rate 100Mbit burst 5000
Also to modify any fields of the hardware context with
NIX_AQ_INSTOP_WRITE command then corresponding masks of those
fields must be set as per hardware. This was missing in
ingress ratelimiting context. This patch sets those masks also.
