- Without this patch in 8021q module, these packets are forwarded to

which should not be the default behaviour, as VLAN 0 is not really
a VLANed packet but a 802.1p packet. Defining VLAN 0 makes it almost
impossible to communicate with mixed 802.1p and non 802.1p devices on
the same network due to arp table issues.
- Changed logic to skip vlan specific code in vlan_skb_recv if VLAN
is 0 and we have not defined a VLAN with ID 0, but we accept the
packet with the encapsulated proto and pass it later to netif_rx.
- In the vlan device event handler, added some logic to add VLAN 0
to HW filter in devices that support it (this prevented any traffic
in VLAN 0 to reach the stack in e1000e with HW filter under 2.6.35,
and probably also with other HW filtered cards, so we fix it here).
- In the vlan unregister logic, prevent the elimination of VLAN 0
in devices with HW filter.
- The default behaviour is to ignore the VLAN 0 tagging and accept
the packet as if it was not tagged, but we can still define a
VLAN 0 if desired (so it is backwards compatible).

packet with the encapsulated proto and pass it later to netif_rx.
- In the vlan device event handler, added some logic to add VLAN 0
to HW filter in devices that support it (this prevented any traffic
in VLAN 0 to reach the stack in e1000e with HW filter under 2.6.35,
and probably also with other HW filtered cards, so we fix it here).
- In the vlan unregister logic, prevent the elimination of VLAN 0
in devices with HW filter.
- The default behaviour is to ignore the VLAN 0 tagging and accept
the packet as if it was not tagged, but we can still define a
VLAN 0 if desired (so it is backwards compatible).
