Subject: [Patch v6 07/22] CIFS: SMBD: Implement function to create a SMB Direct connection
Date: Sat,  4 Nov 2017 22:43:49 -0700	[thread overview]
Message-ID: <20171105054404.23886-8-longli@exchange.microsoft.com> (raw)
In-Reply-To: <20171105054404.23886-1-longli-Lp/cVzEoVyZiJJESP9tAQJZ3qXmFLfmx@public.gmane.org>

From: Long Li <longli-0li6OtcxBFHby3iVrkZq2A@public.gmane.org>

The upper layer calls this function to connect to peer through SMB Direct.
Each SMB Direct connection is based on a RDMA RC Queue Pair.
