Eqos ethernet support five queues on hardware, enable these queues and configure the priority of each queue. Uses Strict Priority as scheduling algorithms to ensure that the TSN function works. The priority of each queue is a bitmask value that maps VLAN tag priority to the queue. Since the hardware only supports five queues, this patch maps priority 0-4 to queues one by one, and priority 5-7 to queue 4. The total fifo size of 5 queues is 8192 bytes, if enable 5 queues with store-and-forward mode, it's not enough for large packets, which would trigger fifo overflow frequently. This patch set DMA to thresh mode to enable all 5 queues.

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.
