So it must come from the Chelsio device then...
Can you provide the max_mr output of the device (you can use
ibv_devinfo -v from libibverbs/ibverbs-utils).
What happens if you use smaller queues, say 64/32 (can be added as a
queue_size parameter working directly from sysfs, nvme-cli does not
support this yet).
Steve, did you see this before? I'm wandering if we need some sort
of logic handling with resource limitation in iWARP (global mrs pool...)
