Currently, the debugfs command for dev capability and dev spec are implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "dev_info" for them, and query them by command "cat dev_info", return the result to userspace, rather than record in dmesg. The display style is below: $cat dev_info dev capability: support FD: yes support GRO: yes support FEC: yes support UDP GSO: no support PTP: no support INT QL: no support HW TX csum: no support UDP tunnel csum: no support TX push: no support imp-controlled PHY: no support rxd advanced layout: no dev spec: MAC entry num: 0 MNG entry num: 0 MAX non tso bd num: 8 RSS ind tbl size: 512 RSS key size: 40 RSS size: 1 Allocated RSS size: 0 Task queue pairs numbers: 1 RX buffer length: 2048 Desc num per TX queue: 1024 Desc num per RX queue: 1024 Total number of enabled TCs: 1 MAX INT QL: 0 MAX INT GL: 8160 MAX TM RATE: 100000 MAX QSET number: 1024 Signed-off-by: Jiaran Zhang <zhangjiaran@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

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.
