When steering to an RXQ, we can perform an extra RSS step to assign a queue from an RSS table. This is done by setting the RSS_EN attribute in the C2 engine. In that case, the RXQ that is assigned is the global RSS context id, that is then translated to an RSS table using the RXQ2RSS table. An example using ethtool to steer to RXQ 2 and 3 would be : ethtool -X eth0 weight 0 0 1 1 context new (This would print the allocated context id, let's say it's 1) ethtool -N eth0 flow-type udp4 dst-port 1234 context 1 loc 0 The hash parameters are the ones that are globally configured for RSS : ethtool -N eth0 rx-flow-hash udp4 sdfn When an RSS context is removed while there are active classification rules using this context, these rules are removed.

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.
