Subject: [PATCH v3 net-next 0/3] bridge: Add vlan filtering support for default pvid

This series adds default pvid support to vlan filtering in the bridge.
VLAN 1 (as recommended by 802.1q spec) is used as default pvid on ports. 
The the user can over-ride this configuration by configuring their
own vlan information. 
The user can additionally change the default value throught the
sysfs interface (netlink comming shortly).
The user can turn off default pvid functionality by setting default
pvid to 0. 
This series changes the default behavior of the bridge when
vlan filtering is turned on.  Currently, ports without any vlan
filtering configured will not recevie any traffic at all.  This patch
changes the behavior of the above ports to receive only untagged traffic.

Since v2:
- Fix handling of invalid values in sysfs interface.
- Add some additional log messages.
- Fix default_pvid handling when vlan filtering is compiled out.
- Fix sparse issues with new code.
- Fix how we located the old default pvid (added a helper function).

Since v1:
- Add ability to turn off default_pvid settings.
- Drop the automiatic filtering support based on configured vlan devices (will
  be its own series)

Thanks
