You're whole argument breaks down because we definitely don't do this
for IPv4 addresses, we'll keep receiving traffic for IPv4 addresses
configured on that interface when received on other interfaces which
are still up, even when you bring that interface down.

Really, if you want to leave GVRP, unconfigure it.

I'm not applying this patch.
