The switch can autocast MIB counter using Ethernet packet. Add support for this and provide a handler for the tagger. The switch will send packet with MIB counter for each port, the switch will use completion API to wait for the correct packet to be received and will complete the task only when each packet is received. Although the handler will drop all the other packet, we still have to consume each MIB packet to complete the request. This is done to prevent mixed data with concurrent ethtool request. connect_tag_protocol() is used to add the handler to the tag_qca tagger, master_state_change() use the MIB lock to make sure no MIB Ethernet is in progress.

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.
