For RX, it has two parts, one is to read data from sdio, another is to indicate the packets to upper stack. Recently it has only one thread to do all RX things, it results that it is sequential for RX and low throughout, change RX to parallel for the two parts will increase throughout. This patch move the indication to a workqueue, it results in significant performance improvement on RX path. Udp rx throughout is 200Mbps without this patch, and it arrives 400Mbps with this patch.

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.
