All the Flow Director rules are stored in tcam blocks. For each bit of tcam entry, the match value depends on two input value(x, y). debugfs command: echo dump fd tcam > cmd Sample output: root@(none)# echo dump fd tcam > cmd hns3 0000:7d:00.0: read result tcam key x(31): hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 08000000 hns3 0000:7d:00.0: 00000600 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: read result tcam key y(31): hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: f7ff0000 hns3 0000:7d:00.0: 0000f900 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 00000000 hns3 0000:7d:00.0: 0000fff8 root@(none)# Signed-off-by: liuzhongzhu <liuzhongzhu@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@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.
