Indeed, I just replicated your problem on my system and confirmed
that the patch adding "srq_attr.srq_type = IB_SRQT_BASIC" does
let mthca devices get through srpt_add_one().  I'll get ready to send
that fix upstream.

It seems quite likely you forgot to install the patched ib_srpt module
or something similar.

Thanks,
  Roland
