Change the inet socket lookup to avoid packets arriving on a device enslaved to an l3mdev from matching unbound sockets by removing the wildcard for non sk_bound_dev_if and instead relying on check against the secondary device index, which will be 0 when the input device is not enslaved to an l3mdev and so match against an unbound socket and not match when the input device is enslaved. Change the socket binding to take the l3mdev into account to allow an unbound socket to not conflict sockets bound to an l3mdev given the datapath isolation now guaranteed.

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.
