2018-10-11mlxsw: spectrum: Seed LAG hash functionIdo Schimmel2-2/+12
Currently, the seed of the LAG hash function is always set to 0, which means it is identical across all switches. Instead, use a random number. This is especially important now that VxLAN is supported, as the LAG hash function is used to calculate the UDP source port of the encapsulated packet.

2018-10-11mlxsw: reg: Extend FDB flush types for NVEIdo Schimmel1-0/+6
The device has the ability to flush all the FDB records that perform NVE encapsulation or only a subset of these with a specific filtering identifier (FID). Expose these types so that they could be used by subsequent patches where we need to flush the FDB records when an NVE device is unlinked from a bridge (FID).

2018-10-11mlxsw: spectrum: Add a new type of KVD linear recordIdo Schimmel2-0/+3
When the device needs to flood an overlay packet to remote VTEPs it retrieves a pointer to the head of a linked-list of records that store the IP addresses of these VTEPs. These records are stored in the KVD linear memory and configured via the Tunneling NVE Underlay Multicast Table (TNUMT) register. Add a new KVD linear entry type for these records, so that we will be able to allocate and free them.

2018-10-10net/mlx5: WQ, fixes for fragmented WQ buffers APITariq Toukan5-32/+23
mlx5e netdevice used to calculate fragment edges by a call to mlx5_wq_cyc_get_frag_size(). This calculation did not give the correct indication for queues smaller than a PAGE_SIZE, (broken by default on PowerPC, where PAGE_SIZE == 64KB). Here it is replaced by the correct new calls/API. Since (TX/RX) Work Queues buffers are fragmented, here we introduce changes to the API in core driver, so that it gets a stride index and returns the index of last stride on same fragment, and an additional wrapping function that returns the number of physically contiguous strides that can be written contiguously to the work queue. This obsoletes the following API functions, and their buggy usage in EN driver: * mlx5_wq_cyc_get_frag_size() * mlx5_wq_cyc_ctr2fragix() The new API improves modularity and hides the details of such calculation for mlx5e netdevice and mlx5_ib rdma drivers. New calculation is also more efficient, and improves performance as follows: Packet rate test: pktgen, UDP / IPv4, 64byte, single ring, 8K ring size.

2018-10-10net/mlx5e: Do not ignore netdevice TX/RX queues numberFeras Daoud7-28/+37
The current design of mlx5e driver ignores the netdevice TX/RX queues number for netdevices that RDMA IPoIB ULP creates. Instead, the queue number is initialized to the maximum number that mlx5 thinks best for performance. As a result, ULP drivers that choose to create a netdevice with queue number that is less than the maximum channels mlx5 creates, will get a memory corruption. This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX queue number and use it when creating resources instead of the maximum channel number.

2018-10-10RDMA/netdev: Hoist alloc_netdev_mqs out of the driverDenis Drozdov1-41/+46
netdev has several interfaces that expect to call alloc_netdev_mqs from the core code, with the driver only providing the arguments. This is incompatible with the rdma_netdev interface that returns the netdev directly. Thus re-organize the API used by ipoib so that the verbs core code calls alloc_netdev_mqs for the driver. This is done by allowing the drivers to provide the allocation parameters via a 'get_params' callback and then initializing an allocated netdev as a second step.

Added support in RVU AF driver to register for CGX LMAC link status change events from firmware and managing them. Processing part will be added in followup patches. - Introduced eventqueue for posting events from cgx lmac.
