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 ]

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 ]

(struct net_device)->garp_port is rcu protected :
(struct garp_port)->applicants is rcu protected :
add __rcu annotation and proper rcu primitives.

vlan: Add GVRP support2008-07-06T04:26:57ZPatrick McHardykaber@trash.net2008-07-06T04:26:57Zurn:sha1:70c03b49b80ba3634958acc31853771019c0ebd3
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.

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.
