ice: Add tc-flower filter support for channel
Add support to add/delete channel specific filter using tc-flower.
For now, only supported action is "skip_sw hw_tc <tc_num>"
Filter criteria is specific to channel and it can be
combination of L3, L3+L4, L2+L4.
Example:
MATCH criteria Action
---------------------------
src and/or dest IPv4[6]/mask -> Forward to "hw_tc <tc_num>"
dest IPv4[6]/mask + dest L4 port -> Forward to "hw_tc <tc_num>"
dest MAC + dest L4 port -> Forward to "hw_tc <tc_num>"
src IPv4[6]/mask + src L4 port -> Forward to "hw_tc <tc_num>"
src MAC + src L4 port -> Forward to "hw_tc <tc_num>"
Adding tc-flower filter for channel using "hw_tc"
-------------------------------------------------
tc qdisc add dev <ethX> clsact
Above two steps are only needed the first time when adding
tc-flower filter.
tc filter add dev <ethX> protocol ip ingress prio 1 flower \
dst_ip 192.168.0.1/32 ip_proto tcp dst_port 5001 \
skip_sw hw_tc 1
tc filter show dev <ethX> ingress
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1 hw_tc 1
eth_type ipv4
ip_proto tcp
dst_ip 192.168.0.1
dst_port 5001
skip_sw
in_hw in_hw_count 1
Delete specific filter:
-------------------------
tc filter del dev <ethx> ingress pref 1 handle 0x1 flower
Delete All filters:
------------------
tc filter del dev <ethX> ingress
