Currently, the driver gets packet type by parsing the L3_ID/L4_ID/OL3_ID/OL4_ID from RX descriptor, it's time-consuming. Now some new devices support RXD advanced layout, which combines previous OL3_ID/OL4_ID to 8bit ptype field, so the driver gets packet type by looking up only one table, and L3_ID/L4_ID become reserved fields. Considering compatibility, the firmware will report capability of RXD advanced layout, the driver will identify and enable it by default. This patch provides basic function: identify and enable the RXD advanced layout, and refactor out hns3_rx_checksum() by using ptype table to handle RX checksum if supported.

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.
