In order to debug performance issue intuitively, add bandwidth information into debugfs entry phy_info. After applying this patch, it looks like: TX rate [0]: HE 2SS MCS-11 GI:0.8 BW:80 (hw_rate=0x19b) ==> agg_wait=1 (3500) RX rate [0]: HE 2SS MCS-9 GI:0.8 BW:80 (hw_rate=0x199) Signed-off-by: Eric Huang <echuang@realtek.com> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20221021091601.39884-1-pkshih@realtek.com
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.
