Add SK_PASS verdict support to SK_SKB_VERDICT programs. Now that support for redirects exists we can implement SK_PASS as a redirect to the same socket. This simplifies the BPF programs and avoids an extra map lookup on RX path for simple visibility cases. Further, reduces user (BPF programmer in this context) confusion when their program drops skb due to lack of support.

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.
