* i40e: warn on newer/older firmware API revShannon Nelson2014-06-24
| | | | | | | | | | | | If the firmware's API minor number is larger than the one expected, log a warning and recommend driver SW update. If the firmware's API major or minor number is smaller then the one expected (n for major, n or n-1 for minor), log a warning and recommend NVM update.

* i40e: Add PF reset when Malicious driver event for PFNeerav Parikh2014-06-24
| | | | | | | | | | | | | | | As per the spec when the PF driver receives a Malicious driver event the queue that caused the event is already stopped and it is expected that the function that owns the queue will reset the queue. In some cases it may not be possible to determine the queue and it is suggested to reset the whole function. This patch takes the later approach when the event is owned by the PF that owns it.

* i40e: make prep_for_reset voidShannon Nelson2014-06-24
| | | | | | | | | | | | The return from i40e_prep_for_reset() was being ignored by almost all its callers. The one place it wasn't ignored could have caused a silent and confusing failure of the driver to finish a reset. Since we really are doing a rebuild anyway, ignore this last case as well and simply make the function a void type.

* i40e: Stop the VF device after setting its MAC addressGreg Rose2014-06-24
| | | | | | | | | | | | | If the host VMM administrator has changed the VF device's MAC address then the i40e driver needs to halt the VF device so that the administrator will be forced to reload the VF driver. This will cause the VF driver to start using the newly assigned MAC address. This brings the i40e driver into conformance with operational characteristics of other Intel SR-IOV featured drivers.

| * enic: Add Accelerated RFS supportGovindarajulu Varadarajan2014-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds supports for Accelerated Receive Flow Steering. When the desired rx is different from current rq, for a flow, kernel calls the driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP hardware filter. Driver registers a timer function enic_flow_may_expire. This function is called every HZ/4 seconds. In this function we check if the added filter has expired by calling rps_may_expire_flow(). If the flow has expired, it removes the hw filter. As of now adaptor supports only IPv4 - TCP/UDP filters. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

Anjali provides an update to the registers to handle the updates from the hardware. Also provides a fix so that we do not try to access the rings through the qvectors at the time of freeing the qvectors. Jesse provides a workaround for some older NVM versions where the NVM was not filling in the GLQF_HKEY register, so made sure that the critical register is initialized. Michal provides a fix to reset the head and tail on admin queue initialization where head and tail are not reset by the hardware. Neerav adds a helper routine that would wait for the Rx/Tx queue to reach the enable or disable state that is requested. Also provides a fix to the debugfs command "lldp get remote" which was dumping the local LLDPDU instead of the peer's LLDPDU. Fixed a bug when all the Tx hang recovery mechanisms have failed and the driver tries to bring down the interface in the interrupt context. Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats when the PF stats are cleared. Also cleans the service tasks so that they do not run while a reset is in progress. Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers were being read instead of all sixteen.

* net: delete duplicate dev_set_rx_mode() callPeter Pan(潘卫平)2014-06-17
| | | | | | | | | | | In __dev_open(), it already calls dev_set_rx_mode(). and dev_set_rx_mode() has no effect for a net device which does not have IFF_UP flag set. So the call of dev_set_rx_mode() is duplicate in __dev_change_flags(). Signed-off-by: Weiping Pan <panweiping3@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* mrf24j40: separate h/w init and add checkingsVarka Bhadram2014-06-17
| | | | | | | | | | | separate the mrf24j40 hardware initialisation from probe() and adds the sanity checkings. These checkings are required if somebody hasn't a right spi configuration the probe function should fail. So we have to return from there.
