Subject: [PATCH 6/9] RDMA/nes: Implement IB_SIGNAL_ALL_WR as an iWARP extension
Date: Tue, 1 Dec 2009 16:19:58 -0600 [thread overview]
Message-ID: <20091201221958.GA6468@ctung-MOBL> (raw)
Add IB_SINGAL_ALL_WR support as an iWARP extension. If set, make
sure all WR for the QP is signalled.
Consolidate flags used in nesqp structure.
