Some older NIC hardware isn't capable of doing VLAN push on RX and pop on TX. A workaround has been added in software to support it, but it has a performance penalty since it requires a hairpin + loopback. There's no such limitation with the newer NICs, so no need to pay the price of the w/a. With this change the software w/a is disabled for certain HW versions and steering modes that support it.

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.
