In multi-queue environment testing, the support for VLAN-tag based steering is useful. So, this patch adds the capability to add VLAN tag (VLAN ID and Priority) to the generated Tx frame. To set the VLAN ID=10 and Priority=2 for Tx only through TxQ=3: $ xdpsock -i eth0 -t -N -z -q 3 -V -J 10 -K 2 If VLAN ID (-J) and Priority (-K) is set, it default to VLAN ID = 1 VLAN Priority = 0. For example, VLAN-tagged Tx only, xdp copy mode through TxQ=1: $ xdpsock -i eth0 -t -N -c -q 1 -V Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Song Liu <songliubraving@fb.com> Link: https://lore.kernel.org/bpf/20211230035447.523177-2-boon.leong.ong@intel.com
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.
