Subject: [PATCH AUTOSEL 4.9 14/21] mlxsw: spectrum: Disallow prio-tagged packets when PVID is removed

From: Ido Schimmel <idosch@...lanox.com>

[ Upstream commit 4b14cc313f076c37b646cee06a85f0db59cf216c ]

When PVID is removed from a bridge port, the Linux bridge drops both
untagged and prio-tagged packets. Align mlxsw with this behavior.

Fixes: 148f472da5db ("mlxsw: reg: Add the Switch Port Acceptable Frame Types register")
