Subject: net/smc: use correct vlan gid of RoCE device
Patch-mainline: v4.19-rc1
Git-commit: 7005ada68d1774d7c1109deaba0c2cd8e46f5091
References: FATE#325698, LTC#167867, bsc#1113481
Description: smc: Latest upstream fixes and extensions up to 8/17/2018
Upstream-Description:
net/smc: use correct vlan gid of RoCE device
SMC code uses the base gid for VLAN traffic. The gids exchanged in
the CLC handshake and the gid index used for the QP have to switch
from the base gid to the appropriate vlan gid.
When searching for a matching IB device port for a certain vlan
device, it does not make sense to return an IB device port, which
is not enabled for the used vlan_id. Add another check whether a
vlan gid exists for a certain IB device port.
