That maybe small flaw in iproute2 - but there's no issue in the kernel.
You can send an ifi and specify the proper ifindex of choice.
But you cant do the same with bridge.
Thats what i was whining to Stephen about. I get every
bridge port with no exception and there's no way to specify one
(the ifi ifindex is never used).
Think 20K bridge ports - each giving me 1K of data ...
scalability problem
