bridge: Allow clearing of pvid and untagged bitmap
Currently, it is possible to modify the vlan filter
configuration to add pvid or untagged support.
For example:
bridge vlan add vid 10 dev eth0
bridge vlan add vid 10 dev eth0 untagged pvid
The second statement will modify vlan 10 to
include untagged and pvid configuration.
However, it is currently impossible to go backwards
bridge vlan add vid 10 dev eth0 untagged pvid
bridge vlan add vid 10 dev eth0
Here nothing happens. This patch correct this so
that any modifiers not supplied are removed from
the configuration.
