Subject: net/mlx5e: E-Switch, Specify flow_source for rule with no in_port
Patch-mainline: v5.8
Git-commit: 6f7bbad18e8343da6318654f408dea0ccd6efb00
References: jsc#SLE-15172
The flow_source must be specified, even for rule without matching
source vport, because some actions are only allowed in uplink.
Otherwise, rule can't be offloaded and firmware syndrome happens.
Fixes: 6fb0701a9cfa ("net/mlx5: E-Switch, Add support for offloading rules with no in_port")
