2015-09-30i40e/i40evf: fix up type clash in i40e_aq_rc_to_posix conversionShannon Nelson1-3/+6

2015-09-29i40e/i40evf: check for stopped admin queueMitch Williams1-0/+9
It's possible that while we are waiting for the spinlock, another entity (that owns the spinlock) has shut down the admin queue. If we then attempt to use the queue, we will panic. Add a check for this condition on the receive side. This matches an existing check on the send queue side.

2015-09-29i40e: fix VLAN inside VXLANJesse Brandeburg1-1/+2
Previously to this patch, the hardware was removing VLAN tags from the inner header of VXLAN packets.

2015-09-29i40e: Fix for recursive RTNL lock during PROMISC changeAnjali Singhai4-14/+19
The sync_vsi_filters function can be called directly under RTNL or through the timer subtask without one. This was causing a deadlock. If sync_vsi_filters is called from a thread which held the lock, and in another thread the PROMISC setting got changed we would be executing the PROMISC change in the thread which already held the lock alongside the other filter update. The PROMISC change requires a reset if we are on a VEB, which requires it to be called under RTNL. Earlier the driver would call reset for PROMISC change without checking if we were already under RTNL and would try to grab it causing a deadlock. This patch changes the flow to see if we are already under RTNL before trying to grab it.

2015-09-29i40e: Fix RS bit update in Tx path and disable force WB workaroundAnjali Singhai2-44/+87
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 and when it does a WB. It also optimizes when we do a wmb.

2015-09-29i40e/i40evf: refactor tx timeout logicKiran Patil4-193/+165
This patch modifies the driver timeout logic by issuing a writeback request via a software interrupt to the hardware the first time the driver detects a hang. The driver was too aggressive in resetting a hung queue, so back that off by removing logic to down the netdevice after too many hangs, and move the function to the service task.

2015-09-02i40e: Set defport behavior for the Main VSI when in promiscuous modeAnjali Singhai Jain2-8/+30
This fixes bugs where the port is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge. In addition, with defport we get VLAN promiscuous behavior which is not possible from the VSI level promiscuous setting.

The kernel notifies all VXLAN capable registered drivers, i.e. any driver that implements ndo_add_vxlan_port(), of the addition of a port so that the driver can track which ports are in use. There's no need to log this - it just fills the system log with useless and irksome noise. Also, when failing to init SR-IOV interfaces the driver was printing the same message twice. Just remove the inner printk and let the outer message catch enable as well as the other failures.

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.

2015-07-23i40e/i40evf: Fix and refactor dynamic ITR codeCarolyn Wyborny1-58/+88
This patch changes the switch statement for dynamic interrupt throttling and adds a default case. With this patch, we check the latency setting instead of the current ITR settings and the included refactor improves performance. Without this patch, the ITR setting would never change dynamically, and there was no default.
