Hi all, This is long overdue, finally add support for VLANs in the Broadcom Starfigther 2 switch driver.
There are a few things that make us differ from e.g; mv88e6xxx.c: - we keep a software cache of which VLANs are enabled and which are not to dramatically speed up the VLAN dump operation, we do not have any HW operation which would only return the list of valid VLAN entries, they would have to be all queried one by one, with 4K vlans, this takes a while - the default behavior is equivalent to setting VLAN filtering to 1, still working on implementing a proper port_vlan_filtering callback, but I figured the most conservative behavior is probably okay anyway - without enabling VLANs, the default behavior is to receive any 802.1q frames (per the DSA documentation), however, once we start enabling VLAN support, if an interface leaves the bridge, we still want it to receive all 802.1q frames so we utiliez the "Join all VLAN" feature of the switch to perform that Thanks!
