From dfb5fa32c66496a53ec6a45302d902416b51ade2 Mon Sep 17 00:00:00 2001 From: Toshiaki Makita Date: Wed, 16 Oct 2013 17:07:16 +0900 Subject: bridge: Fix updating FDB entries when the PVID is applied We currently set the value that variable vid is pointing, which will be used in FDB later, to 0 at br_allowed_ingress() when we receive untagged or priority-tagged frames, even though the PVID is valid. This leads to FDB updates in such a wrong way that they are learned with VID 0. Update the value to that of PVID if the PVID is applied.
