[ Upstream commit6113cc4401] Two flow specifications can set the ip protocol field in the flow table entry: 1) IB_FLOW_SPEC_TCP/UDP/GRE - set the ip protocol accordingly. 2) IB_FLOW_SPEC_IPV4/6 - has ip_protocol field for users who want to receive specific L4 packets. We need to avoid overriding of the ip_protocol with zeros, in case that the user first put the L4 specification and only then the L3.

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.
