> Flow domain and direction was validated when OF_PUSH_VLAN action

> 
> - was used in NIC domain, in ingress direction;
> - was used in FDB domain, in ingress direction, on ConnectX-5.

> This patch moves code responsible for OF_PUSH_VLAN validation of

> flow_dv_validate(). Domain and direction are now validated when either
> non-hairpin queue is used or hairpin queue is configured in Tx explicit
