Linux kernel source tree
8416814fff
This implements XDP hints kfunc for RX-hash (xmo_rx_hash). The HW rss hash type is handled via mapping table. This igc driver (default config) does L3 hashing for UDP packets (excludes UDP src/dest ports in hash calc). Meaning RSS hash type is L3 based. Tested that the igc_rss_type_num for UDP is either IGC_RSS_TYPE_HASH_IPV4 or IGC_RSS_TYPE_HASH_IPV6. This patch also updates AF_XDP zero-copy function igc_clean_rx_irq_zc() to use the xdp_buff wrapper struct igc_xdp_buff.

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.
