Implement dedicated route entry infrastructure to be used in following patch by route update event. Both encap (indirectly through their corresponding encap entries) and decap (directly) flows are attached to routing entry. Since route update also requires updating encap (route device MAC address is a source MAC address of tunnel encapsulation), same encap_tbl_lock mutex is used for synchronization. The new infrastructure looks similar to existing infrastructures for shared encap, mod_hdr and hairpin entries: - Per-eswitch hash table is used for quick entry lookup. - Flows are attached to per-entry linked list and hold reference to entry during their lifetime. - Atomic reference counting and rcu mechanisms are used as synchronization primitives for concurrent access. The infrastructure also enables connection tracking on stacked devices topology by attaching CT chain 0 flow on tunneling dev to decap route entry.

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.
