Erm...one of the firmware versions that I downloaded with tvflash.
Non trivial to say since /sys/class/infiniband isn't available.

Either fw3.3 or hca-cougar-a1-250-157.bin.
Because tvflash can't identify it, I'll guess it's the fw3.3
(a version of HP's firmware that exposes the 3rd MMIO BAR).

I can try again on another machine that has the hca-cougar
firmware.
