Subject: [Patch v2 04/19] CIFS: SMBD: Add SMBDirect transport to SMB connection and Makefile
Date: Sun, 20 Aug 2017 12:04:28 -0700	[thread overview]
Message-ID: <1503255883-3041-5-git-send-email-longli@exchange.microsoft.com> (raw)
In-Reply-To: <1503255883-3041-1-git-send-email-longli@exchange.microsoft.com>

From: Long Li <longli@microsoft.com>

Add SMBDirect as an optional connection to SMB session defined in CIFS. When connection is on SMBDirect, upper layer uses this connection to carry payloads.

With the transport hooked up, add SMBDirect code to Makefile.
