[Bridge] [PATCH 0/3] bridge: Some nice new things for vlan filtering

[Vladislav Yasevich <vyasevich@gmail.com>]

While working with vlan filtering and non-promisc mode, I've found
myself wanting untagged traffic to automatically pass through the
bridge.  So I decided to introduce the concept of a per bridge default
pvid.  VLAN 1 is used as default pvid by default and can be changed
by user through sysfs while vlan filtering is off. (I'll be adding netlink
support now that Jiri Pirko kindly added the ifrastructure).  Default
pvid is assigned to all ports that do not assign their own pvid or
already have a given vlan configured.  This makes it very simple
to enable vlan filtering on the bridge, not have to configure a thing,
and still pass untagged traffic.

The other small thing this series adds is automatic update of the
vlan filter when vlan is configured on top of the bridge.  In this
case we automatically add the given vlan to the bridge filter list.
The ports may still need to be updated as we don't know which ports
are allowed to receive a given vlan.

Thanks
