Magnus Karlsson says: ==================== xsk: support redirect to any socket bound to the same umem This patch set adds support for directing a packet to any socket bound to the same umem. This makes it possible to use the XDP program to select what socket the packet should be received on. The user can populate the XSKMAP with various sockets and as long as they share the same umem, the XDP program can pick any one of them. The implementation is straight-forward. Instead of testing that the incoming packet is targeting the same device and queue id as the socket is bound to, just check that the umem the packet was received on is the same as the socket we want it to be received on. This guarantees that the redirect is legal as it is already in the correct umem. Patch #1 implements the feature and patch #2 adds documentation.

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.
