Based on the mac80211's TXQ implementation, TX-AMSDU can be used to get higher MAC efficiency. To make mac80211 aggregate MSDUs, low level driver just need to leave skbs in the TXQ, and mac80211 will try to aggregate them if possible. As driver will schedule a tasklet when the TX queue is woke, until the tasklet being served, there will have some skbs in the queue if traffic is heavy. Driver can control the max AMSDU size depending on the current bit rate used by hardware/firmware. The higher rates are used, the larger AMSDU size can be. It is tested that can achieve higher T-Put at higher rates. If the environment is relatively clean, and the bit_rate is high enough, we can get about 80Mbps improvement. For lower bit rates, not much gain can we get, so leave the max_amsdu length low to prevent aggregation.

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.
