Allow to match on vrf slave ifindex or name. In case there was no slave interface involved, store 0 in the destination register just like existing iif/oif matching. sdif(name) is restricted to the ipv4/ipv6 input and forward hooks, as it depends on ip(6) stack parsing/storing info in skb->cb[].

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.
