2016-04-12ath10k: remove MSI range supportRajkumar Manoharan
MSI-X is never well-tested, might contain bugs and generally isn't really all that useful to maintain. Also ath10k is mainly used with shared/singly-MSI interrupt systems. Hence removing MSI range support. This change will be useful for further cleanup in copy engine lock and to add NAPI support.

2016-04-09ibmvnic: Enable use of multiple tx/rx scrqsJohn Allen
Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.

2016-04-08net: dsa: make the VLAN add function return voidVivien Didelot
The switchdev design implies that a software error should not happen in the commit phase since it must have been previously reported in the prepare phase. If an hardware error occurs during the commit phase, there is nothing switchdev can do about it. The DSA layer separates port_vlan_prepare and port_vlan_add for simplicity and convenience. If an hardware error occurs during the commit phase, there is no need to report it outside the driver itself. Make the DSA port_vlan_add routine return void for explicitness.

2016-04-08nfp: convert .ndo_change_mtu() to prepare/commit paradigmJakub Kicinski
When changing MTU on running device first allocate new rings and buffers and once it succeeds proceed with changing MTU. Allocation of new rings is not really necessary for this operation - it's done to keep the code simple and because size of the extra ring memory is quite small compared to the size of buffers. Operation can still fail midway through if FW communication times out. In that case we retry with old MTU (rings). Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2016-04-08nfp: sync ring state during FW reconfigurationJakub Kicinski
FW reconfiguration in .ndo_open()/.ndo_stop() should reset/ restore queue state. Since we need IRQs to be disabled when filling rings on RX path we have to move disable_irq() from .ndo_open() all the way up to IRQ allocation. nfp_net_start_vec() becomes trivial now so it's inlined.

2016-04-08nfp: preallocate RX buffers early in .ndo_openJakub Kicinski
We want the .ndo_open() to have following structure: - allocate resources; - configure HW/FW; - enable the device from stack perspective.

2016-04-08nfp: reorganize initial filling of RX ringsJakub Kicinski
Separate allocation of buffers from giving them to FW, thanks to this it will be possible to move allocation earlier on .ndo_open() path and reuse buffers during runtime reconfiguration. Similar to TX side clean up the spill of functionality from flush to freeing the ring. Unlike on TX side, RX ring reset does not free buffers from the ring. Ring reset means only that FW pointers are zeroed and buffers on the ring must be placed in [0, cnt - 1) positions.

2016-04-08nfp: move link state interrupt request/free callsJakub Kicinski
We need to be able to disable the link state interrupt when the device is brought down. We used to just free the IRQ at the beginning of .ndo_stop(). As we now move towards more ordered .ndo_open()/.ndo_stop() paths LSC allocation should be placed in the "allocate resource" section.
