The patch seems to solve a case of possible "live lock" happening in a
node which has both CM and datagram neighbors e.g where ipoib have
called netif_stop etc but there is now room in the QP for more postings

CQ would have been polled. Its hard to see how this relates to the post
send error print

I posted a patch that does this, but I think it missed the 2.6.34 merge
cycle.
