Eli Cohen f0dc117abd IPoIB: Fix TX queue lockup with mixed UD/CM traffic ... The IPoIB UD QP reports send completions to priv->send_cq, which is usually left unarmed; it only gets armed when the number of outstanding send requests reaches the size of the TX queue. This arming is done only in the send path for the UD QP. However, when sending CM packets, the net queue may be stopped for the same reasons but no measures are taken to recover the UD path from a lockup. Consider this scenario: a host sends high rate of both CM and UD packets, with a TX queue length of N. If at some time the number of outstanding UD packets is more than N/2 and the overall outstanding packets is N-1, and CM sends a packet (making the number of outstanding sends equal N), the TX queue will be stopped. When all the CM packets complete, the number of outstanding packets will still be higher than N/2 so the TX queue will not be restarted. Fix this by calling ib_req_notify_cq() when the queue is stopped in the CM path.
