Thank you for the confirmation that the byte counters are a factor of 4. I suspect you are right about the packet counters as well... I will double check.
It's too bad "perfquery" doesn't work in a RoCE network. We are not running a subnet agent on this linux server. (Should we be running a subnet agent? But that would require a subnet manager somewhere, right?)
# perfquery
ibwarn: [8397] mad_rpc_open_port: can't open UMAD port ((null):0)
perfquery: iberror: failed: Failed to open '(null)' port '0'
