Subject: [PATCH v2 net-next 08/10] net: dsa: pass extack to .port_bridge_join driver methods
As FDB isolation cannot be enforced between VLAN-aware bridges in lack
of hardware assistance like extra FID bits, it seems plausible that many
DSA switches cannot do it. Therefore, they need to reject configurations
with multiple VLAN-aware bridges from the two code paths that can
transition towards that state:
- joining a VLAN-aware bridge
- toggling VLAN awareness on an existing bridge
The .port_vlan_filtering method already propagates the netlink extack to
the driver, let's propagate it from .port_bridge_join too, to make sure
that the driver can use the same function for both.
