commitb7e945e228upstream. The sixth byte of packet data has to be looked up in the sixth group, not in the seventh one, even if we load the bucket data into ymm6 (and not ymm5, for convenience of tracking stalls). Without this fix, matching on a MAC address as first field of a set, if 8-bit groups are selected (due to a small set size) would fail, that is, the given MAC address would never match.

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.
