2016-08-19hv_netvsc: Implement batching of receive completionsHaiyang Zhang
The existing code uses busy retry when unable to send out receive completions due to full ring buffer. It also gives up retrying after limit is reached, and causes receive buffer slots not being recycled. This patch implements batching of receive completions. It also prevents dropping receive completions due to full ring buffer.

Correcting the mutex usage, in client_subtask(), mutex_unlock has to be called just before client_del_instance() since this function opens and later closes the same mutex again. Similarly in client_is_registered removing the mutex since it closes the mutex twice. This is a patch suggested by RDMA team.

2016-08-19drm/vc4: Fix overflow mem unreferencing when the binner runs dry.Eric Anholt
Overflow memory handling is tricky: While it's still referenced by the BPO registers, we want to keep it from being freed. When we are putting a new set of overflow memory in the registers, we need to assign the old one to the last rendering job using it. We were looking at "what's currently running in the binner", but since the bin/render submission split, we may end up with the binner completing and having no new job while the renderer is still processing. So, if we don't find a bin job at all, look at the highest-seqno (last) render job to attach our overflow to.

It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities.

The mv88e6xxx driver times out operations on the switch based on looping until an elapsed wall clock time is reached.

So replace the elapsed time with a fixed upper bound on the number of loops.

2016-08-19net: hns: Add reset function support for RoCE driveroulijun
It added reset function for RoCE driver. RoCE is a feature of hns. In hip06 SoC, in RoCE reset process, it's needed to configure dsaf channel reset, port and sl map info. Reset function of RoCE is located in dsaf module, we only call it in RoCE driver when needed.

2016-08-19net/mlx5: E-Switch, Avoid ACLs in the offloads modeOr Gerlitz
When we are in the switchdev/offloads mode, HW matching is done as dictated by the offloaded rules and hence we don't need to enable the ACLs mechanism used by the legacy mode.

2016-08-19net/mlx5: E-Switch, Set the send-to-vport rules in the correct tableOr Gerlitz
While adding actual offloading support to the new switchdev mode, we didn't change the setup of the send-to-vport rules to put them in the slow path table, fix that.

2016-08-19net/mlx5: E-Switch, Return the correct devlink e-switch modeOr Gerlitz
Since mlx5 has also the NONE e-switch mode, we must translate from mlx5 mode to devlink mode on the devlink eswitch mode get call, do that. While here, remove the mlx5_ prefix from the static function helpers that deal with the mode to comply with the rest of the code.

2016-08-19net/mlx5: Added missing check of msg length in verifying its signaturePaul Blakey
Set and verify signature calculates the signature for each of the mailbox nodes, even for those that are unused (from cache). Added a missing length check to set and verify only those which are used. While here, also moved the setting of msg's nodes token to where we already go over them. This saves a pass because checksum is disabled, and the only useful thing remaining that set signature does is setting the token.
