[ Upstream commit f480851981043d9bb6447ca9883ade9247b9a0ad ]
Currently the PVID of ports are only set when adding/updating VLANs with
PVID set or removing VLANs, but not when clearing the PVID flag of a
VLAN.
E.g. the following flow
$ ip link add br0 type bridge vlan_filtering 1
$ ip link set sw1p1 master bridge
$ bridge vlan add dev sw1p1 vid 10 pvid untagged
$ bridge vlan add dev sw1p1 vid 10 untagged
Would keep the PVID set as 10, despite the flag being cleared. Fix this
by checking if we need to unset the PVID on vlan updates.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
