Subject: [PATCH net-next 0/2] Simplify DSA handling of VLAN subinterface offload

Depends on Vivien Didelot's patchset:
https://patchwork.ozlabs.org/project/netdev/list/?series=127197&state=*

This patchset removes a few strange-looking guards for -EOPNOTSUPP in
dsa_slave_vlan_rx_add_vid and dsa_slave_vlan_rx_kill_vid, making that
code path no longer possible.

It also disables the code path for the sja1105 driver, which does
support editing the VLAN table, but not hardware-accelerated VLAN
sub-interfaces, therefore the check in the DSA core would be wrong.
There was no better DSA callback to do this than .port_enable, i.e.
at ndo_open time.

Vladimir Oltean (2):
  net: dsa: Advertise the VLAN offload netdev ability only if switch
    supports it
  net: dsa: sja1105: Clear VLAN filtering offload netdev feature
