[PATCH rdma-rc 0/3] mlx5 and NLDEV fixes

[PATCH rdma-rc 0/3] mlx5 and NLDEV fixes

[Leon Romanovsky]

Hi Doug,

There are three patches targeted for this -RC, while mlx5 patches can
easily go to -next, the nldev patch better to be forwarded to Linus in
this cycle.

Because, we are in -rc7 now, I would really appreciate to hear your
plans regarding nldev patch.

The patches are available in the git repository at:
  git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git tags/rdma-rc-2017-10-30

	Thanks

[PATCH rdma-rc 1/3] IB/mlx5: Assign send CQ and recv CQ of UMR QP

[Leon Romanovsky]

From: Majd Dibbiny <majd-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The UMR's QP is created by calling mlx5_ib_create_qp directly, and
therefore the send CQ and the recv CQ on the ibqp weren't assigned.

Assign them right after calling the mlx5_ib_create_qp to assure
that any access to those pointers will work as expected and won't
crash the system as might happen as part of reset flow.

[PATCH rdma-rc 2/3] IB/mlx5: Fix RoCE Address Path fields

[Leon Romanovsky]

From: Majd Dibbiny <majd-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

When working over a RoCE network, the UDP source port should be set only
for statically connected QPs (RC, UC and XRC).

[PATCH rdma-rc 3/3] RDMA/nldev: Enforce device index check for port callback

[Leon Romanovsky]

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

IB device index is nldev's handler and it should be always checked.

This went into -rc7 direct from you to Linus, so I dropped it here.

But I went ahead and took these two.  Thanks.
