When removing last vlan from a device, garp_uninit_applicant() calls
synchronize_rcu() to make sure no user can still manipulate struct
garp_applicant before we free it.Use call_rcu() instead, as a step to further net_device dismantle
optimizations.Add the temporary garp_cleanup_module() function to make sure no pending
call_rcu() are left at module unload time [ this will be removed when
kfree_rcu() is available ]Signed-off-by: Eric Dumazet

Speedup vlan dismantling in CONFIG_VLAN_8021Q_GVRP=y cases,
by using a call_rcu() to free the memory instead of waiting with
expensive synchronize_rcu() [ while RTNL is held ]Signed-off-by: Eric Dumazet

Add GVRP support for dynamically registering VLANs with switches.
By default GVRP is disabled because we only support the applicant-only
participant model, which means it should not be enabled on vlans that
are members of a bridge. Since there is currently no way to cleanly
determine that, the user is responsible for enabling it.The code is pretty small and low impact, its wrapped in a config
option though because it depends on the GARP implementation and
the STP core.Signed-off-by: Patrick McHardy

Add an implementation of the GARP (Generic Attribute Registration Protocol)
applicant-only participant. This will be used by the following patch to
add GVRP support to the VLAN code.Signed-off-by: Patrick McHardy
