2015-12-01i40evf: create a generic get RSS functionHelin Zhang
There are two ways to get RSS, this patch implements two functions with the same input parameters, and creates a more generic function for getting RSS configuration.

2015-12-01i40e/i40evf: Fix RS bit update in Tx path and disable force WB workaroundAnjali Singhai Jain
This patch fixes the issue of forcing WB too often causing us to not benefit from NAPI. Without this patch we were forcing WB/arming interrupt too often taking away the benefits of NAPI and causing a performance impact. With this patch we disable force WB in the clean routine for X710 and XL710 adapters. X722 adapters do not enable interrupt to force a WB and benefit from WB_ON_ITR and hence force WB is left enabled for those adapters. For XL710 and X710 adapters if we have less than 4 packets pending a software Interrupt triggered from service task will force a WB. This patch also changes the conditions for setting RS bit as described in code comments. This optimizes when the HW does a tail bump amd when it does a WB. It also optimizes when we do a wmb.

2015-12-01hv_netvsc: rework link status change handlingVitaly Kuznetsov
There are several issues in hv_netvsc driver with regards to link status change handling: - RNDIS_STATUS_NETWORK_CHANGE results in calling userspace helper doing '/etc/init.d/network restart' and this is inappropriate and broken for many reasons. - link_watch infrastructure only sends one notification per second and in case of e.g. paired disconnect/connect events we get only one notification with last status. This makes it impossible to handle such situations in userspace. Redo link status changes handling in the following way: - Create a list of reconfig events in network device context. - On a reconfig event add it to the list of events and schedule netvsc_link_change(). - In netvsc_link_change() ensure 2-second delay between link status changes. - Handle RNDIS_STATUS_NETWORK_CHANGE as a paired disconnect/connect event.

2015-12-01iwlwifi: mvm: ROC: Extend the ROC max delay duration & limit ROC durationMatti Gottlieb
When associated to an AP and a ROC event with a long duration is scheduled the FW may have a hard time scheduling a consecutive time event, since it has to remain on the connection channel to hear the AP's DTIM. In addition, when associated and a ROC is requested with a duration greater than the DTIM interval, the FW will not be able to schedule the ROC event, since it needs to wake up for the DTIM. Increasing the "max delay" duration to the DTIM period will allow the FW to wait until after the DTIM and then schedule the ROC time event. Limiting the ROC to be less than the DTIM interval will assure that the time event will be scheduled for at least part of the time (instead of automatically failing) Extend the ROC max delay duration to min(dtim_interval * 3, 600TU), and limit the duration to be less than the DTIM interval.
