[Patch v3 04/19] CIFS: SMBD: Add SMBDirect transport to SMB connection and Makefile

[Long Li <longli@exchange.microsoft.com>]

From: Long Li <longli@microsoft.com>

Add SMBDirect as an optional connection to the SMB session structure in CIFS.
When SMB session is connected through SMBDirect, upper layer uses this
connection to carry payloads.

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