* nfp: flower: offload merge flowsJohn Hurley2019-04-161-0/+1
| | | | | | | | | | | | | | | A merge flow is formed from 2 sub flows. The match fields of the merge are the same as the first sub flow that has formed it, with the actions being a combination of the first and second sub flow. Therefore, a merge flow should replace sub flow 1 when offloaded. Offload valid merge flows by using a new 'flow mod' message type to replace an existing offloaded rule. Track the deletion of sub flows that are linked to a merge flow and revert offloaded merge rules if required.

| | | | | | | | | | | | | | If a merge hint is received containing 2 flows that are matched via an implicit recirculation (sending to and matching on an internal port), fw reports that the flows (called sub_flows) may be able to be combined to a single flow.

* nfp: flower: allow offloading of matches on 'internal' portsJohn Hurley2019-04-161-0/+7
| | | | | | | | | | | | | | | | | | | | | Recent FW modifications allow the offloading of non repr ports. These ports exist internally on the NFP. So if a rule outputs to an 'internal' port, then the packet will recirculate back into the system but will now have this internal port as it's incoming port. These ports are indicated by a specific type field combined with an 8 bit port id. Add private app data to assign additional port ids for use in offloads. Provide functions to lookup or create new ids when a rule attempts to match on an internal netdev - the only internal netdevs currently supported are of type openvswitch. Have a netdev notifier to release port ids on netdev unregister. OvS offloads rules that match on internal ports as TC egress filters. Ensure that such rules are accepted by the driver.

* nfp: flower: increase cmesg reply timeoutFred Lotter2019-01-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QA tests report occasional timeouts on REIFY message replies. Profiling of the two cmesg reply types under burst conditions, with a 12-core host under heavy cpu and io load (stress --cpu 12 --io 12), show both PHY MTU change and REIFY replies can exceed the 10ms timeout. The maximum MTU reply wait under burst is 16ms, while the maximum REIFY wait under 40 VF burst is 12ms. Using a 4 VF REIFY burst results in an 8ms maximum wait. A larger VF burst does increase the delay, but not in a linear enough way to justify a scaled REIFY delay. The worse case values between MTU and REIFY appears close enough to justify a common timeout. Pick a conservative 40ms to make a safer future proof common reply timeout. The delay only effects the failure case. Change the REIFY timeout mechanism to use wait_event_timeout() instead of wait_event_interruptible_timeout(), to match the MTU code. In the current implementation, theoretically, a signal could interrupt the REIFY waiting period, with a return code of ERESTARTSYS. However, this is caught under the general timeout error code EIO. I cannot see the benefit of exposing the REIFY waiting period to signals with such a short delay (40ms), while the MTU mechnism does not use the same logic. In the absence of any reply (wakeup() call), both reply types will wake up the task after the timeout period. The REIFY timeout applies to the entire representor group being instantiated (e.g. VFs), while the MTU timeout apples to a single PHY MTU change.

A prelag action is also offloaded which must be the first action of the series (although may appear after other pre-actions - e.g. tunnels). This causes the FW to check that it has the necessary information to output to the requested LAG port. If it does not, the packet is sent to the kernel before any other actions are applied to it.

* nfp: flower: offload phys port MTU changeJohn Hurley2018-03-301-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Trigger a port mod message to request an MTU change on the NIC when any physical port representor is assigned a new MTU value. The driver waits 10 msec for an ack that the FW has set the MTU. If no ack is received the request is rejected and an appropriate warning flagged. Rather than maintain an MTU queue per repr, one is maintained per app. Because the MTU ndo is protected by the rtnl lock, there can never be contention here. Portmod messages from the NIC are also protected by rtnl so we first check if the portmod is an ack and, if so, handle outside rtnl and the cmsg work queue. Acks are detected by the marking of a bit in a portmod response. They are then verfied by checking the port number and MTU value expected by the app. If the expected MTU is 0 then no acks are currently expected. Also, ensure that the packet headroom reserved by the flower firmware is considered when accepting an MTU change on any repr.

* nfp: flower vxlan neighbour keep-aliveJohn Hurley2017-09-271-0/+1
| | | | | | | | | | | | | | | Periodically receive messages containing the destination IPs of tunnels that have recently forwarded traffic. Update the neighbour entries 'used' value for these IPs next hop. This prevents the neighbour entry from expiring on timeout but rather signals an ARP to verify the connection. From an NFP perspective, packets will not fall back mid-flow unless the link is verified to be down.

* nfp: flower vxlan neighbour offloadJohn Hurley2017-09-271-0/+2
| | | | | | | | | | | | | Receive a request when the NFP does not know the next hop for a packet that is to be encapsulated in a VXLAN tunnel. Do a route lookup, determine the next hop entry and update neighbour table on NFP. Monitor the kernel neighbour table for link changes and update NFP with relevant information. Overwrite routes with zero values on the NFP when they expire.

* nfp: offload flower vxlan endpoint MAC addressesJohn Hurley2017-09-271-0/+9
| | | | | | | | | | | | | | | | | | | Generate a list of MAC addresses of netdevs that could be used as VXLAN tunnel end points. Give offloaded MACs an index for storage on the NFP in the ranges: 0x100-0x1ff physical port representors 0x200-0x2ff VF port representors 0x300-0x3ff other offloads (e.g. vxlan netdevs, ovs bridges) Assign phys and vf indexes based on unique 8 bit values in the port num. Maintain list of other netdevs to ensure same netdev is not offloaded twice and each gets a unique ID without exhausting the entries. Because the IDs are unique but constant for a netdev, any changes are implemented by overwriting the index on NFP.

* nfp: add control message passing capabilities to flower offloadsPieter Jansen van Vuuren2017-07-011-0/+6
| | | | | | | | | | | | | | | | | Previously the flower offloads never sends messages to the hardware, and never registers a handler for receiving messages from hardware. This patch enables the flower offloads to send control messages to hardware when adding and removing flow rules. Additionally it registers a control message rx handler for receiving stats updates from hardware for each offloaded flow. Additionally this patch adds 4 control message types; Add, modify and delete flow, as well as flow stats. It also allows nfp_flower_cmsg_get_data() to be used outside of cmsg.c.
