I'm assuming that the interesting part is the 20 Gbits/s capture? And at minimum packet sizes, I'd hope. Linux has been able to stream more than 5 GBytes/s (40 Gbits/s) to disk for several years now over SRP.

You may find it easier to use a recent RedHat or SUSE with an upstream kernel. I know that RHEL6 userland is compatible with the upstream kernel's Infiniband, and OFED is moving its kernel work to a "backport upstream" model for OFED 3.2.

Indeed it does.
