[PATCH rdma-next V1 00/19] RDMA Netlink Device Client

[Leon Romanovsky <leon@kernel.org>]

Hi All,

This is second version of the RDMA netlink patch set.

The following patch set is an implementation of NLDEV - RDMA netlink
device client. It is based on the already sent patch [1] and patch set [2].

This client is needed to properly integrate coming RDMAtool [3]
into iproute2 package which is based on netlink.

The following patch set can be logically divided into four parts:
 * Cleanup of RDMA netlink interface to handle dumpit/doit callbacks.
 * Implementation of static ib_device index to allow future renaming support for IB devices.
 * NLDEV initial implementation
 * Exposing device and capability masks via this interface

The supplementary user space part will follow later on.

Chagelog:
v0->v1:
 * Added Steve's Reviewed-by tags for all patches except patch #8, because it was completely rewritten.
 * Implemented static indexes for ib_device in patch #8 and dropped preview version which
   translated device name to corresponding ib_device.
 * Fixed language in commit messages as was pointed by Steve.
 * Rename TODO to be FIXME in patch #11.

Thanks
