Subject: [PATCH] CIFS: SMBD: Upper layer reconnects to SMB Direct session
Git-commit: 781a8050f2a8e1474a75122b7d940959cc579e14
Patch-mainline: v4.15
References: bsc#1144333
Do a reconnect on SMB Direct when it is used as the connection. Reconnect can
happen for many reasons and it's mostly the decision of SMB2 upper layer.
