Subject: [PATCH for-next 09/10] IB/mlx5: Eliminate GSI RX QP's send buffers
Date: Mon, 29 Feb 2016 15:45:11 +0200	[thread overview]
Message-ID: <1456753512-17688-10-git-send-email-haggaie@mellanox.com> (raw)
In-Reply-To: <1456753512-17688-1-git-send-email-haggaie-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Now that the transmission of GSI MADs is done with the special transmission
QPs, eliminate the send buffers in the GSI receive QP.
