net: microchip: sparx5: Adding initial tc flower support for VCAP API
This adds initial TC flower filter support to Sparx5 for the IS2 VCAP.
The support consists of the source and destination MAC addresses,
and the trap and pass actions.
This is how you can create a rule that test the functionality:
tc qdisc add dev eth0 clsact
tc filter add dev eth0 ingress chain 8000000 prio 10 handle 10 \
protocol all flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap
The IS2 chains in Sparx5 are assigned like this:
- chain 8000000: IS2 Lookup 0
- chain 8100000: IS2 Lookup 1
- chain 8200000: IS2 Lookup 2
- chain 8300000: IS2 Lookup 3
