From: Dmytro Linkin <dmitrolin@xxxxxxxxxxxx>
[ Upstream commit d5dbcc4e87bc8444bd2f1ca4b8f787e1e5677ec2 ]
Termination tables are used for vlan push actions on uplink ports.
To support RoCE dual port the source port value was placed in a register.
Fix the code to use an API method returning the source port according to
the FW capabilities.
Fixes: 10caabdaad5a ("net/mlx5e: Use termination table for VLAN push actions")
