Add support for 802.1ad VLAN devices. This mainly consists of checking for
ETH_P_8021AD in addition to ETH_P_8021Q in a couple of places and check
offloading capabilities based on the used protocol.
Configuration is done using "ip link":
# ip link add link eth0 eth0.1000 \
type vlan proto 802.1ad id 1000
# ip link add link eth0.1000 eth0.1000.1000 \
type vlan proto 802.1q id 1000
52:54:00:12:34:56 > 92:b1:54:28:e4:8c, ethertype 802.1Q (0x8100), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84)
20.1.0.2 > 20.1.0.1: ICMP echo request, id 3003, seq 8, length 64
92:b1:54:28:e4:8c > 52:54:00:12:34:56, ethertype 802.1Q-QinQ (0x88a8), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 47944, offset 0, flags [none], proto ICMP (1), length 84)
20.1.0.1 > 20.1.0.2: ICMP echo reply, id 3003, seq 8, length 64

---help---
|
|
Select this and you will be able to create 802.1Q VLAN interfaces
|
|
on your ethernet interfaces. 802.1Q VLAN supports almost
|
|
everything a regular ethernet interface does, including
|
|
firewalling, bridging, and of course IP traffic. You will need
|
|
the 'vconfig' tool from the VLAN project in order to effectively
|
|
use VLANs. See the VLAN web page for more information:

|
To compile this code as a module, choose M here: the module
|
|
will be called 8021q.
|
|
|
|
If unsure, say N.

Select this to enable GVRP end-system support. GVRP is used for
|
|
automatic propagation of registered VLANs to switches.

If unsure, say N.

|
|
help
|
|
Select this to enable MVRP end-system support. MVRP is used for
|
|
automatic propagation of registered VLANs to switches; it
|
|
supersedes GVRP and is not backwards-compatible.
|
|
|
|
If unsure, say N.
