Edward Cree says: ==================== sfc: ARFS fixes Three issues introduced by my recent asynchronous filter handling changes: 1. The old filter_rfs_insert would replace a matching filter of equal priority; we need to pass the appropriate argument to filter_insert to make it do the same. 2. We're lying to the kernel with our return value from ndo_rx_flow_steer, so we need to lie consistently when calling rps_may_expire_flow. This is only a partial fix, as the lie still prevents us from steering multiple flows with the same ID to different queues; a proper fix that stops us lying at all will hopefully follow later. 3. It's possible to cause the kernel to hammer ndo_rx_flow_steer very hard, so make sure we don't build up too huge a backlog of workitems. Possibly it would be better to fix #3 on the kernel side; I have a patch which I think does that but it's not a regression in 4.17 so isn't 'net' material. There's also the issue that we come up in the bad configuration that triggers #3 by default, but that too is a problem for another time. ==================== Signed-off-by: David S.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
