Tristram Ha says: ==================== net: dsa: microchip: add MIB counters support This series of patches is to modify the KSZ9477 DSA driver to read MIB counters periodically to avoid overflow. The MIB counters should be read only when there is link. Otherwise it is a waste of time as hardware never increases the counters. Functions are added to check the port link status so that MIB counters read call is used efficiently. v4 - Use readx_poll_timeout - Fix using mutex in a timer callback function problem - use dp->slave directly instead of checking whether it is valid - Add port_cleanup function in a separate patch - Add a mutex so that changing device variables is safe v3 - Use netif_carrier_ok instead of checking the phy device pointer v2 - Create macro similar to readx_poll_timeout to use with switch - Create ksz_port_cleanup function so that variables like on_ports and live_ports can be updated inside it v1 - Use readx_poll_timeout - Do not clear MIB counters when port is enabled - Do not advertise 1000 half-duplex mode when port is enabled - Do not use freeze function as MIB counters may miss counts ==================== 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.
