hw_ifidx was originally introduced to store the real netdevice as a
requirement for the hardware offload support in:
73f97025a9 ("netfilter: nft_flow_offload: use direct xmit if hardware offload is enabled")
Since ("netfilter: flowtable: consolidate xmit path"), ifidx and
hw_ifidx points to the real device in the xmit path, remove it.

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 reStructuredText 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.
