Since commit 856dfd69e84f ("fm10k: Fix multicast mode synch issues",
2016-03-03) we've incorrectly assumed that VLAN 1 is enabled when the
default VID is not set.
This occurs because we check the default_vid and if it's zero, start
several loops over the active_vlans bitmask at 1, instead of checking to
ensure that that bit is active.
This happened because of commit d9ff3ee8efe9 ("fm10k: Add support for
VLAN 0 w/o default VLAN", 2014-08-07) which mistakenly assumed that we
should send requests for MAC and VLAN filters with VLAN 0 when the
default_vid isn't set.
However, the switch generally considers this an invalid configuration,
so the only time we'd have a default_vid of 0 is when the switch is
down.
Instead, lets just not request any filters for the default_vid if it's
not yet been assigned.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
