Previously, trying to insert an ip4/ip6 ntuple rule with an unset
l4proto would get rejected with -EOPNOTSUPP. For example, the following
would fail:
ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1
The reason was that all the l4proto validation was being run despite the
l4proto mask being set to 0x0. Fix by respecting the mask on l4proto and
treating a mask of 0x0 as wildcard l4proto.

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 reStructuredText 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.
