Allow efx_tc_encap_match entries to include an ip_tos and ip_tos_mask. To avoid partially-overlapping Outer Rules (which can lead to undefined behaviour in the hardware), store extra "pseudo" entries in our encap_match hashtable, which are used to enforce that all Outer Rule entries within a given <src_ip,dst_ip,udp_dport> tuple (or IPv6 equivalent) have the same ip_tos_mask. The "direct" encap_match entry takes a reference on the "pseudo", allowing it to be destroyed when all "direct" entries using it are removed. efx_tc_em_pseudo_type is an enum rather than just a bool because in future an additional pseudo-type will be added to support Conntrack offload.

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.
