Parav Pandit be5914c124 RDMA/core: Delete RoCE GID in hw when corresponding IP is deleted 
Currently a RoCE GID entry is removed from the hardware when all
references to the GID entry drop to zero. This is a change in behavior
from before the fixed patch. The GID entry should be removed from the
hardware when GID entry deletion is requested. This allows the driver
terminate ongoing traffic through the RoCE GID.

While a GID is deleted from the hardware, GID slot in the software GID
cache is not freed. GID slot is freed once all references of such GID are
dropped. This continue to ensure that such GID slot of hardware is not
allocated to new GID entry allocation request. It is allocated once all
references to GID entry drop.

This approach allows drivers to put a tombestone of some kind on the HW
GID index to block the traffic.

README 

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.
