Currently, the debugfs command for queue info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create two files "rx_queue_info" and "tx_queue_info" for it, and query it by command "cat rx_queue_info" and "cat tx_queue_info", return the result to userspace, rather than record in dmesg. The display style is below: $ cat rx_queue_info QUEUE_ID BD_NUM BD_LEN TAIL HEAD FBDNUM PKTNUM ... 0 0 0 0 0 0 0 ... 1 0 0 0 0 0 0 ... 2 0 0 0 0 0 0 ... $ cat tx_queue_info QUEUE_ID BD_NUM TC TAIL HEAD FBDNUM OFFSET PKTNUM ... 0 0 0 0 0 0 0 0 ... 1 0 0 0 0 0 0 0 ... 2 0 0 0 0 0 0 0 ...

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.
