Currently dsa_port_vid_add returns 0 if the switch returns -EOPNOTSUPP. This function is used in the tag_8021q.c code to offload the PVID of ports, which would simply not work if .port_vlan_add is not supported by the underlying switch. Do not skip -EOPNOTSUPP in dsa_port_vid_add but only when necessary, that is to say in dsa_slave_vlan_rx_add_vid. Signed-off-by: Vivien Didelot <vivien.didelot@gmail.com> Signed-off-by: David S.

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.
