[PATCH rdma-next V1 0/4] ConnectX-3 RSS Implementation

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

Hi Doug,

This patch set adds to ConnectX-3 devices the ability to use RSS
feature, which was initially implemented in mlx5-based devices [1].

The backport of RSS feature to ConnectX-3 hardware was a challenge
task due to differences in architectures between mlx4 and mlx5 based
devices.

It caused to a limited number of usage limitations, mentioned in the relevant
commit messages where it applies.

This series supports all RSS related verbs.

Thanks.

Changelog:
v0->v1:
 * Removed limitation of number of WQs per context which was 128.
 * Added unlimited number of ranges of WQs according to provided user data.
