Add a netevent callback for cma, mainly to catch NETEVENT_NEIGH_UPDATE. Previously, when a system with failover MAC mechanism change its MAC address during a CM connection attempt, the RDMA-CM would take a lot of time till it disconnects and timesout due to the incorrect MAC address. Now when we get a NETEVENT_NEIGH_UPDATE we check if it is due to a failover MAC change and if so, we instantly destroy the CM and notify the user in order to spare the unnecessary waiting for the timeout.

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.
