net: dsa: Add more convenient functions for installing port VLANs
This hides the need to perform a two-phase transaction and construct a switchdev_obj_port_vlan struct. Call graph (including a function that will be introduced in a follow-up patch) looks like this now (same for the *_vlan_del function): dsa_slave_vlan_rx_add_vid dsa_port_setup_8021q_tagging | | | | | +-------------+ | | v v dsa_port_vid_add dsa_slave_port_obj_add | | +-------+ +-------+ | | v v dsa_port_vlan_add Signed-off-by: Vladimir Oltean <olteanv@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
