Thanks, these are interesting counters. Unfortunately these counters
are 32-bit counters and already overflowed during the test I ran (less
than one day of SRP communication):
$ uname -r
2.6.24
$ uname -m
x86_64
$ head /sys/class/infiniband/mthca0/ports/1/counters/*_{data,packets}
==> /sys/class/infiniband/mthca0/ports/1/counters/port_rcv_data <==
