Crud, I see a bug with that commit and non-SRQ:
ipoib_cm_handle_tx_wc() does

       struct ipoib_cm_tx *tx = wc->qp->qp_context;

and there's no reason for wc->qp to be set if the HCA does not handle
SRQs.  In fact there's no reason for wc->qp to be set for send
completions in general.

Not sure if this is the problem you're seeing, but now I need to
figure out how to fix it...
