The mac80211 provides software TX queue for driver, as long as driver has hooked ieee80211_ops::wake_tx_queue. Each time a packet is queued onto the TX queue, that queue will be woken up the inform driver to serve the queue. Now driver only supports PCI interface ICs, there's no specific traffic control for each queue, just schedule a tasklet, and dump all of the packets at once to the DMA ring. Instead of TX the packets whenever TX queue is woke, tasklet handler can have more packets dumped to the device, takes advantage of burst write with DMA engine. And if the driver is going to support USB/SDIO ICs, the tasklet can be more flexible for aggregating the packets, enhance the efficiency of bandwidth usage.

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.
