During link creation add net-device ifindex and ib-device name to link structure. This is needed for diagnostic purposes. When diagnostic information is gathered, we need to traverse device, linkgroup and link structures, to be able to do that we need to hold a spinlock for the linkgroup list, without this diagnostic information in link structure, another device list mutex holding would be necessary to dereference the device pointer in the link structure which would be impossible when holding a spinlock already.

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.
