[PATCH rdma-next v1 0/2] UAPI cleanup and fix to cxgb3 removal

[Leon Romanovsky]

From: Leon Romanovsky <leonro@mellanox.com>

Chagelog:
 v0->v1: https://lore.kernel.org/linux-rdma/20191010192053.GD11569@mellanox.com
 * Split one patch to two.
 * Added RDMA_DRIVER_CXGB3 back instead of mangling with rdma_driver_id.

Thanks

[PATCH rdma-next v1 1/2] RDMA/uapi: Fix and re-organize the usage of rdma_driver_id

[Leon Romanovsky]

From: Yishai Hadas <yishaih@mellanox.com>

Fix 'enum rdma_driver_id' to preserve other driver values before that
RDMA_DRIVER_CXGB3 was deleted. As this value is UAPI we can't affect
other values as of a deletion of one driver id.

Fixes: 30e0f6cf5acb ("RDMA/iw_cxgb3: Remove the iw_cxgb3 module from kernel")

[Leon Romanovsky]

From: Yishai Hadas <yishaih@mellanox.com>

Drop the dependency of ib_user_ioctl_verbs.h on ib_user_verbs.h which
is not really required.

Still don't understand why this is being moved here, not  this one:

>  struct ib_uverbs_query_port_resp_ex {

>  	__u16 port_cap_flags2;

Moved to its proper place

Neither of these belong in this header
