CPSW: Policer color marking issue

Details:

Only applies to CPSW9G and CPSW5G.

When packets from two different ports hit the same policer such that one port has a large packet and the other has a short packet and the short packet arrives just after the large packet starts, the short packet will stop the backlog counting, resulting in potentially flagging the next frame for this policer as yellow when it should have been green. Because the policer is normally set up to not drop yellow, it should not cause an issue. This is only true of packets that arrive on different ports that share the same policer index.

Workaround(s):

Ensure policers are unique to ports.
