[PATCH net 2/2] selftests: net: bridge: test ranges with PVID VLAN

[Nikolay Aleksandrov <razor@blackwall.org>]

Add a test with PVID VLAN that matches the flags of the VLAN following it
and check if the range is properly dumped. PVID VLAN should be on its own
and all VLANs should be present in the dump.
