2016-09-24Bluetooth: BCSP fails to ACK re-transmitted frames from the peerDean Jenkins
Send an ACK frame with the current txack value in response to every received reliable frame unless a TX reliable frame is being sent. This modification allows re-transmitted frames from the remote peer to be acknowledged rather than ignored. It means that the remote peer knows which frame number to start re-transmitting from. Without this modification, the recovery time to a missing frame from the remote peer was unnecessarily being extended because the headers of the out of order reliable frames were being discarded rather than being processed. The frame headers of received frames will indicate whether the local peer's transmissions have been acknowledged by the remote peer. Therefore, the local peer may unnecessarily re-transmit despite the remote peer already indicating that the frame had been acknowledged in out of order reliable frame.

2016-09-23net/mlx5: E-Switch, Support VLAN actions in the offloads modeOr Gerlitz
Many virtualization systems use a policy under which a vlan tag is pushed to packets sent by guests, and popped before the packet is forwarded to the VM. The current generation of the mlx5 HW doesn't fully support that on a per flow level. As such, we are addressing the above common use case with the SRIOV e-Switch abilities to push vlan into packets sent by VFs and pop vlan from packets forwarded to VFs. The HW can match on the correct vlan being present in packets forwarded to VFs (eSwitch steering is done before stripping the tag), so this part is offloaded as is. A common practice for vlans is to avoid both push vlan and pop vlan for inter-host VM/VM (east-west) communication because in this case, push on egress cancels out with pop on ingress. For supporting that, we use a global eswitch vlan pop policy, hence allowing guest A to communicate with both remote VM B and local VM C. This works since the HW pops the vlan only if it exists (e.g for C --> A packets but not for B --> A packets). On the slow path, when a VF vport has an offloaded flow which involves pushing vlans, wheres another flow is not currently offloaded, the packets from the 2nd flow seen by the VF representor on the host have vlan. The VF rep driver removes such vlan before calling into the host networking stack.

2016-09-23ixgbe: Support 4 queue RSS on VFs with 1 or 2 queue RSS on PFAlexander Duyck
Instead of limiting the VFs if we don't use 4 queues for RSS in the PF we can instead just limit the RSS queues used to a power of 2. By doing this we can support use cases where VFs are using more queues than the PF is currently using and can support RSS if so desired. The only limitation on this is that we cannot support 3 queues of RSS in the PF or VF. In either of these cases we should fall back to 2 queues in order to be able to use the power of 2 masking provided by the psrtype register.

2016-09-22i40e: Limit TX descriptor count in cases where frag size is greater than 16KAlexander Duyck
The i40e driver was incorrectly assuming that we would always be pulling no more than 1 descriptor from each fragment. It is in fact possible for us to end up with the case where 2 descriptors worth of data may be pulled when a frame is larger than one of the pieces generated when aligning the payload to either 4K or pieces smaller than 16K. To adjust for this we just need to make certain to test all the way to the end of the fragments as it is possible for us to span 2 descriptors in the block before us so we need to guarantee that even the last 6 descriptors have enough data to fill a full frame.

There is a sanitcy check for desc being null in the first line of function i40evf_debug_aq.
