The easiest way to simulate stripped VLAN tag in veth is to send a packet from VLAN interface, attached to veth. Unfortunately, this approach is incompatible with AF_XDP on TX side, because VLAN interfaces do not have such feature. Check both packets sent via AF_XDP TX and regular socket. AF_INET packet will also have a filled-in hash type (XDP_RSS_TYPE_L4), unlike AF_XDP packet, so more values can be checked.

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.
