Ansuel Smith says: ==================== net: Reduce qca8k_priv space usage These 6 patch is a first attempt at reducting qca8k_priv space. The code changed a lot during times and we have many old logic that can be replaced with new implementation The first patch drop the tracking of MTU. We mimic what was done for mtk and we change MTU only when CPU port is changed. The second patch finally drop a piece of story of this driver. The ar8xxx_port_status struct was used by the first implementation of this driver to put all sort of status data for the port... With the evolution of DSA all that stuff got dropped till only the enabled state was the only part of the that struct. Since it's overkill to keep an array of int, we convert the variable to a simple u8 where we store the status of each port. This is needed to don't reanable ports on system resume. The third patch is a preparation for patch 4. As Vladimir explained in another patch, we waste a tons of space by keeping a duplicate of the switch dsa ops in qca8k_priv. The only reason for this is to dynamically set the correct mdiobus configuration (a legacy dsa one, or a custom dedicated one) To solve this problem, we just drop the phy_read/phy_write and we declare a custom mdiobus in any case. This way we can use a static dsa switch ops struct and we can drop it from qca8k_priv Patch 4 drop the duplicated dsa_switch_ops. Patch 5 is a fixup for mdio read error. Patch 6 is an effort to standardize how bus name are done. This series is just a start of more cleanup. The idea is to move this driver to the qca dir and split common code from specific code. Also the mgmt eth code still requires some love and can totally be optimized by recycling the same skb over time. Also while working on the MTU it was notice some problem with the stmmac driver and with the reloading phase that cause all sort of problems with qca8k. I'm sending this here just to try to keep small series instead of proposing monster series hard to review. v2: - Rework MTU patch v3: - Drop unrealated changes from patch 3 - Add fixup patch for mdio read - Unify bus name for legacy and OF mdio bus ==================== 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.
