====================
Marvell Prestera add flower and match all support
Add ACL infrastructure for Prestera Switch ASICs family devices to
offload cls_flower rules to be processed in the HW.
ACL implementation is based on tc filter api. The flower classifier
is supported to configure ACL rules/matches/action.
Supported actions:
- drop
- trap
- pass
Supported dissector keys:
- indev
- src_mac
- dst_mac
- src_ip
- dst_ip
- ip_proto
- src_port
- dst_port
- vlan_id
- vlan_ethtype
- icmp type/code
- Introduce matchall filter support
- Add SPAN API to configure port mirroring.
- Add tc mirror action.
At this moment, only mirror (egress) action is supported.
Example:
tc filter ... action mirred egress mirror dev DEV
v2:
Fixed "newline at EOF warnings" from "git am" by
re-applying with --whitespace=fix
patch #1:
1) Set TC HW Offload always enabled without disable it [suggested by Vladimir Oltean]
by user. It reduced the logic by removing feature
handling and acl block disable counting.
patch #2:
1) Removed extra not needed diff with prestera_port and [suggested by Vladimir Oltean]
prestera_switch lines exchanging in prestera_acl.h
2) Fix local variables ordering to reverse chrostmas tree [suggested by Vladimir Oltean]
3) Use tc_cls_can_offload_and_chain0() in [suggested by Vladimir Oltean]
prestera_span_replace()
4) Removed TODO about prio check [suggested by Vladimir Oltean]
5) Rephrase error message if prestera_netdev_check() [suggested by Vladimir Oltean]
fails in prestera_span_replace()
