Using QLogic dual port HCAs, this works for me when I disable port 1 on the
client, server, or both while the test is running:
# qperf <server ipaddr> -ap 2 -t 30 rc_bw
rc_bw:
warning: -ap set but not used in test rc_bw
bw = 272 MB/sec
The warning can be ignored. Using -ap is equivalent to using -rap and -lap
with the same port.
The "failed to receive results" is qperf saying that once the test finished,
the server did not contact the client.
