Pull rdma fixes from Doug Ledford:
"I had thought at the time of the last pull request that there wouldn't
be much more to go, but several things just kept trickling in over the
last week.
Instead of just the six patches to bnxt_re that I had anticipated,
there are another five IPoIB patches, two qedr patches, and a few
other miscellaneous patches.
The bnxt_re patches are more lines of diff than I like to submit this
late in the game. That's mostly because of the first two patches in
the series of six. I almost dropped them just because of the lines of
churn, but on a close review, a lot of the churn came from removing
duplicated code sections and consolidating them into callable
routines. I felt like this made the number of lines of change more
acceptable, and they address problems, so I left them. The remainder
of the patches are all small, well contained, and well understood.
These have passed 0day testing, but have not been submitted to
linux-next (but a local merge test with your current master was
without any conflicts).
Summary:
- A fix for fix eea40b8f624 ("infiniband: call ipv6 route lookup via
the stub interface")
- Six patches against bnxt_re...the first two are considerably larger
than I would like, but as they address real issues I went ahead and
submitted them (it also helped that a good deal of the churn was
removing code repeated in multiple places and consolidating it to
one common function)
- Two fixes against qedr that just came in
- One fix against rxe that took a few revisions to get right plus
time to get the proper reviews
- Five late breaking IPoIB fixes
- One late cxgb4 fix"

When trapped on WARN_ON(), report_bug() is expected to return
BUG_TRAP_TYPE_WARN so the caller will increment NIP by 4 and continue.
The __builtin_constant_p() path of the PPC's WARN_ON()
calls (indirectly) __WARN_FLAGS() which has BUGFLAG_WARNING set,
however the other branch does not which makes report_bug() report a

====================
mlx4 XDP performance improvements
This patchset contains data-path improvements, mainly for XDP_DROP
and XDP_TX cases.
Main patches:
* Patch 2 by Saeed allows enabling optimized A0 RX steering (in HW) when
setting a single RX ring.
With this configuration, HW packet-rate dramatically improves,
reaching 28.1 Mpps in XDP_DROP case for both IPv4 (37% gain)
and IPv6 (53% gain).
* Patch 6 enhances the XDP xmit function. Among other changes, now we
ring one doorbell per NAPI. Patch gives 17% gain in XDP_TX case.
* Patch 7 obsoletes the NAPI of XDP_TX completion queue and integrates its
poll into the respective RX NAPI. Patch gives 15% gain in XDP_TX case.

Some code re-ordering, functionally equivalent.
- The !tx_info->inl check is evaluated anyway in both flows
(common case/end case). Run it first, this might finish
the flows earlier.
- dma_unmap calls are identical in both flows, get it out
of the if block into the common area.
Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Gain is too small to be measurable, no degradation sensed.
Results are similar for IPv4 and IPv6.

Increase the default TX ring size (from 512 to 1024) to match
the RX ring size.
This gives the XDP TX ring a better chance to keep up with the
rate of its RX ring in case of a high load of XDP_TX actions.

Instead of having their own NAPIs, XDP TX completion queues get
polled within the corresponding RX NAPI.
This prevents any possible race on TX ring prod/cons indices,
between the context that issues the transmits (RX NAPI) and the
context that handles the completions (was previously done in
a separate NAPI).
This also improves performance, as it decreases the number
of NAPIs running on a CPU, saving the overhead of syncing
and switching between the contexts.

- Compiler branch predictor hints.
- Calculate values in compile time rather than in runtime.

Mellanox mlx5 fixes 2017-06-14
This series contains some fixes for the mlx5 core and netdev driver.
Please pull and let me know if there's any problem.
For -stable:
("net/mlx5: Wait for FW readiness before initializing command interface") kernels >= 4.4
("net/mlx5e: Fix timestamping capabilities reporting") kernels >= 4.5
("net/mlx5e: Avoid doing a cleanup call if the profile doesn't have it") kernels >= 4.9
("net/mlx5e: Fix min inline value for VF rep SQs") kernels >= 4.11
The "net/mlx5e: Fix min inline .." (a oneliner patch) doesn't cleanly apply
to 4.11, it hits a contextual conflict and can be easily resolved by:
+ mlx5_query_min_inline(mdev, &priv->params.tx_min_inline_mode);
to the end of mlx5e_build_rep_netdev_priv. Note the 2nd parameter of
mlx5_query_min_inline is slightly different from the original one.

Adding a support to flush all HW resources with one FW command and
skip all the heavy unload flows of the driver on kernel shutdown.
There's no need to free all the SW context since a new fresh kernel
will be loaded afterwards.
Regarding the FW resources, they should be closed, otherwise we will
have leakage in the FW. To accelerate this flow, we execute one command
in the beginning that tells the FW that the driver isn't going to close
any of the FW resources and asks the FW to clean up everything.
Once the commands complete, it's safe to close the PCI resources and
finish the routine.

Unlike ethtool stats, get_stats ndo provides information cached by
update stats work that is running in the background without updating
them explicitly.
We cannot update all counters inside the ndo because some
updates require firmware commands that cannot be performed under a
spinlock.
update_stats work does not need to update ALL counters, since only
some of them are needed by ndo_get_stats.
This patch will allow for a minimal run of update_stats using an extra
parameter which will update necessary counters only and cut 13
firmware commands in each iteration of the work.
Work duration previous to this patch: ~4200us.
Work duration after this patch: ~700us (17% of the original time).

For a better code reuse and readability, use the existing
function arfs_get_tt() to map arfs_type into mlx5e_traffic_types,
instead of duplicating the switch-case logic.

LAG cannot work if virtual functions are present. Therefore, if LAG is
configured, the attempt to create virtual functions will fail. This gives
precedence to LAG over SRIOV which is not the desired behavior as users
might want to use the bonding/teaming driver also want to work with SRIOV.
In that case we don't want to force an order of actions, first create
virtual functions and only than configure a bonding/teaming net device.
To fix, if LAG is configured during a request to create virtual
functions, remove it and continue.
We ignore ENODEV when trying to forbid lag. This makes sense
because "No such device" means that lag is forbidden anyway.

The error flow of mlx5e_create_netdev calls the cleanup call
of the given profile without checking if it exists, fix that.
Currently the VF reps don't register that callback and we crash
if getting into error -- can be reproduced by the user doing ctrl^C
while attempting to change the sriov mode from legacy to switchdev.

Currently the firmware API is partial and allows to offload only
the dscp part of the tos, also, ipv6 support isn't there yet.
As such, remove the offloading option of ipv4 dscp till the FW
APIs are more comprehensive.

The offending commit only changed the code path for PF/VF, but it
didn't take care of VF representors. As a result, since
params->tx_min_inline_mode for VF representors is kzalloced to 0
(MLX5_INLINE_MODE_NONE), all VF reps SQs were set to that mode.
This actually works on CX5 by default but broke CX4. Fix that by
adding a call to query the min inline mode from the VF rep build up code.
