When BROPT_FDB_LOCAL_VLAN_0 is enabled, the local FDB entries for member ports should not be created per-VLAN, but instead only on VLAN 0. When the member port address changes, the local FDB entries need to be updated, which is done in br_fdb_changeaddr(). Under the VLAN-0 mode, only one local FDB entry will ever be added for a port's address, and that on VLAN 0. Thus bail out of the delete loop early. For the same reason, also skip adding the per-VLAN entries.

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 reStructuredText 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.
