[PATCH v2] net: dsa: lan9303: add VLAN IDs to master device

From: Mans Rullgard <hidden>
Date: 2022-02-16 20:48:30
Also in: lkml
Subsystem: networking drivers, networking [dsa], the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Andrew Lunn, Vladimir Oltean, Linus Torvalds

If the master device does VLAN filtering, the IDs used by the switch
must be added for any frames to be received.  Do this in the
port_enable() function, and remove them in port_disable().

Signed-off-by: Mans Rullgard <redacted>
