Jonas Gorski says: ==================== net: dsa: b53: fix ARL accesses for BCM5325/65 and allow VID 0 ARL entries on BCM5325 and BCM5365 were broken significantly in two ways: - Entries for the CPU port were using the wrong port id, pointing to a non existing port. - Setting the VLAN ID for entries was not done, adding them all to VLAN 0 instead. While the former technically broke any communication to the CPU port, with the latter they were added to the currently unused VID 0, so they never became effective. Presumably the default PVID was set to 1 because of these issues 0 was broken (and the root cause not found). So fix writing and reading entries on BCM5325/65 by first fixing the CPU port entries, then fixing setting the VLAN ID for entries. Finally, re-allow VID 0 for BCM5325/65 to allow the whole 1-15 VLAN ID range to be available to users, and align VLAN handling with all other switch chips. ==================== Link: https://patch.msgid.link/20251128080625.27181-1-jonas.gorski@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
