Protect vlan_unconfig with a mutex
It is not thread-safe but is likely to be executed in concurrent.
See PR 49264 for more detail.
--
Tweak vlan_unconfig
No functional change.
--
Add handling of VLAN packets in if_bridge where the parent interface supports
them (Jean-Jacques.Puig%espci.fr@localhost). Factor out the vlan_mtu enabling and
disabling code.
--
Enable the VLAN mtu capability and check for the adjusted packet size
(Jean-Jacques.Puig at espci.fr).
Factor out the packet-size checking function for clarity.
--
Don't increment the reference count only when it was 0...
>From Jean-Jacques.Puig
--
Account for the CRC len (Jean-Jacques.Puig)
--
Fix a bug that the parent interface's callback wasn't called when the vlan
interface is configured. A callback function uses VLAN_ATTACHED() function
which check ec->ec_nvlans, the value should be incremented before calling the
callback. This bug was added in if_vlan.c rev. 1.83 (2015/11/19).
