2015-08-06i40e/i40evf: Add support for writeback on ITR feature for X722Anjali Singhai Jain4-9/+42
X722 fixes an issue from X710 where TX descriptor WB would not happen if the interrupts were disabled. In order for the write backs to happen a bit needs to be set in the dynamic interrupt control register called WB_ON_ITR. With this feature, the SW driver need not arm SW interrupts to work around the issue in X710.

2015-08-06i40e/i40evf: RSS changes for X722Anjali Singhai Jain5-46/+155
X722 uses the admin queue to configure RSS. This patch adds the necessary flow changes to configure RSS through AQ. It also adds the separate VMDQ2 lookup tables and hash key programming for X722. X722 also exposes a different set of PCTYPES for RSS, this patch accommodates those changes.

2015-07-23i40e: provide correct API version to older VF driversMitch Williams1-0/+3
This driver fully supports VF drivers using both the 1.0 and 1.1 versions of the virtual channel API. However, VF drivers using version 1.0 get upset if we provide them with a version other than that, and refuse to play with us. Correct this by checking the VFs API version at the time that we store it off, and provide the correct version number back to the VF so we can all get along.

2015-07-23i40e: add VF capabilities to virtual channel interfaceMitch Williams1-5/+11
To prepare for the changes coming up in the X722 device and future devices, the virtual channel interface has to change slightly. The VF driver can now report what its capable of supporting, which then informs the PF driver when it sends the configuration information back to the VF. A 1.1 VF driver on a 1.0 PF driver should not send its capabilities. Likewise, a 1.1 PF driver controlling a 1.0 VF driver should not expect or depend upon receiving the VF capabilities. All other aspects of the API are unchanged.

2015-06-23switchdev; add VLAN support for port's bridge_getlinkScott Feldman1-2/+2
One more missing piece of the puzzle. Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg. Before this patch, "bridge vlan show": $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlans 57 sw1p1 << device side vlans (missing) sw1p2 57 sw1p2 sw1p3 sw1p4 br0 None (When the port is bridged, the output repeats the vlan list for the vlans on the bridge side of the port and the vlans on the device side of the port. The listing above show no vlans for the device side even though they are installed). After this patch: $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlan 57 sw1p1 30-34 << device side vlans 57 3840 PVID sw1p2 57 sw1p2 57 3840 PVID sw1p3 3842 PVID sw1p4 3843 PVID br0 None I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func. switchdev support adds an obj dump for VLAN objects, using the same call-back scheme as FDB dump.

2015-06-05i40e: start up in VEPA mode by defaultAnjali Singhai Jain4-5/+36
The patch fixes a bug in the default configuration which prevented a software bridge loaded on the PF interface from working correctly because broadcast packets are incorrectly looped back. Fix the general case, by loading the driver in VEPA mode Until a VF or VMDq VSI is added. This way loopback on the Main VSI is turned off until needed and can resolve the issue of unnecessary reflection for users that do not have VF or VMDq VSIs setup. The driver must now coordinate the loopback setting for the Flow Director (FDIR) VSI to make sure it is in sync with the current VEB or VEPA mode setting. The user can still switch bridge modes from the bridge commands and choose to be in VEPA mode with VF VSIs. Because of hardware requirements, the call to switch to VEB mode when no VF/VMDqs are present will be rejected. NOTE: This patch uses BIT_ULL as that is preferred going forward, a followup patch in the lower priority queue to net-next will fix up the remaining 1 << usages.

2015-05-28i40e/i40evf: Add ATR support for tunneled TCP/IPv4/IPv6 packets.Anjali Singhai Jain2-33/+45
Without this, RSS would have done inner header load balancing. Now we can get the benefits of ATR for tunneled packets to better align TX and RX queues with the right core/interrupt.

2015-05-28i40e: Disable offline diagnostics if VFs are enabledGreg Rose2-0/+34
Require the user to disable virtual functions before running the device offline diagnostics. The offline diagnostics are intended to ensure basic operation of the device - it is beyond the scope of the diagnostic test to handle the additional complexity of bringing all the virtual functions offline and then back online for each test run.

2015-05-28i40e: Collect PFC XOFF RX stats even in single TC caseNeerav Parikh1-3/+2
When PFC is enabled for any UP in single TC configuration the driver didn't collect the PFC XOFF RX stats. Though a single TC with PFC enabled is not a common scenario do not prevent the driver from collecting stats if firmware indicates that PFC is enabled.

NLM_F_MULTI must be used only when a NLMSG_DONE message is sent. In fact, it is sent only at the end of a dump. Libraries like libnl will wait forever for NLMSG_DONE.
