From the source code of the qlnxe(8) driver, it has a sysctl tunable
`dev.xx.[0-9].dp_level` which is default 1. Turn that to 0 the driver will emit
verbose log which would be very useful.

I do not have that hardware so not sure what's the detailed knob, maybe it is
`dev.ql.0.dp_level` or `dev.qlnxe.0.dp_level`. You can find and confirm the
sysctl tunable by `sysctl dev | grep dp_level`.

I'd recommend you redo the test after change `dp_level`, and share the system
log (/var/log/message).

Well, some versions are also helpful. They can be obtained via sysctl knobs
`dev.xx.[0-9].Driver_Version` `dev.xx.[0-9].STORMFW_Version` and
`dev.xx.[0-9].MFW_Version`.
