Description

At some setups we see Cisco Fabricpath Traffic (ethertype 0x8903) that results in rather high drop rates even though the traffic is not responsible for much load. With a bpf filter to that protocol the issue was gone.

Do you have more info about what you're seeing? Any decoder events, perf stats, etc?

Two systems with no filter active (case a) and bpf filter active (case b). Also a perf top from those machines running without the bpf filter. The left one is another machine with low traffic and not that much traffic at all but quite some amount of it being cisco fabric path.

I didn't had a change to find it yet, when I zoom in I see nothing. I agree that this is rather strange.

Btw - there are some functions/calls that can be unknown , just havn't seen an "unknown" with so high usage - was my point.
