This patch goes though and cleans up the logic related to several of the

The segmentation code was having to do a bunch of work to pull the

when addresses used in the provider network overlap with addresses in

BRIDGE_VLAN_FILTERING automatically adds a newly bridged port to the
VLAN with the bridge's default_pvid.
The mv88e6xxx driver currently reserves VLANs 4000+ for unbridged ports
isolation. When a port joins a bridge, it leaves its reserved VLAN. When
a port leaves a bridge, it joins again its rese
The current bridge code calls switchdev_port_obj_del on a VLAN port even
if the corresponding switchdev_port_obj_add call returned -EOPNOTSUPP.
If the DSA driver doesn't return -EOPNOTSUPP for a software port VLAN in
its port_vlan_del function, the VLAN is not deleted. Unbridging the port

This is from the hit-the-code-until-it-confesses department:
--- a/drivers/isdn/gigaset
Allows the ht_caps mcs rxmask to be defined on the fly.
In this implementation, the given rxmask is applied to
every band available.
This is only applicable for radio cards without internal rc.

This patchset allows the ht_caps mcs rxmask to be defined on the fly.
It applies the given rxmask to all available bands.
This is actually limited to radio cards without internal rc.
