interface

Hello,

Is it possible to obtain statistics about the amount of RDMA traffic
that passed over an InfiniBand interface ? While it is easy to obtain
the number of bytes that has been communicated via IPoIB (e.g. via the
command head /sys/class/net/ib*/statistics/*), I do not know of any way
to observe the non-IPoIB traffic that passes over an InfiniBand
interface. This would be convenient to observe iSER / SRP traffic.

Bart.
