Saeed Mahameed says: ==================== Mellanox 100G mlx5 updates 2016-11-29 The following series from Tariq and Roi, provides some critical fixes and updates for the mlx5e driver. From Tariq: - Fix driver coherent memory huge allocation issues by fragmenting completion queues, in a way that is transparent to the netdev driver by providing a new buffer type "mlx5_frag_buf" with the same access API. - Create UMR MKey per RQ to have better scalability. From Roi: - Some fixes for the encap-decap support and tc flower added lately to the mlx5e driver. v1->v2: - Fix start index in error flow of mlx5_frag_buf_alloc_node, pointed out by Eric.

In Striding RQ implementation, we used a single UMR (User-Mode Memory Registration) memory key for all RQs. When the product of RQs number*size gets high, we hit a limitation of u16 field size in FW. Here we move to using a UMR memory key per RQ, so we can scale to any number of rings, with the maximum buffer size in each. Signed-off-by:

Add new type of struct mlx5_frag_buf which is used to allocate fragmented buffers rather than contiguous, and make the Completion Queues (CQs) use it as they are big (default of 2MB per CQ in Striding RQ). This fixes the failures of type: "mlx5e_open_locked: mlx5e_open_channels failed, -12" due to dma_zalloc_coherent insufficient contiguous coherent memory to satisfy the driver's request when the user tries to setup more or larger rings.

Neill Whillans says: ==================== net: Add support for SGMII PCS on Altera TSE MAC These patches were created as part of work to add support for SGMII PCS functionality to the Altera TSE MAC. Patches are based on 4.9-rc6 git tree. The first patch in the series adds support for the VSC8572 dual-port Gigabit Ethernet transceiver, used in integration testing. The second patch adds support for the SGMII PCS functionality to the Altera TSE driver. ==================== Signed-off-by: -
Neill Whillans authored
Add support for the (optional) SGMII PCS functionality of the Altera TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover and initialise the PCS so that the MAC can communicate to the PHY. The PCS IP block provides a scratch register for testing presence of the PCS, which is mapped into one of the two MDIO spaces present in the MAC's register space. Once we have determined that the scratch register is functioning, we attempt to initialise the PCS to auto-negotiate an SGMII link with the PHY. There is no need to monitor or manage the SGMII link beyond this, since the normal PHY MDIO will then be used to monitor the media layer. The Altera TSE MAC has only one way in which it can be configured with an SGMII PCS, and as such, this patch only looks to the phy-mode to select whether or not to attempt to initialise the PCS registers. During initialisation, we report the PCS's equivalent of a PHY ID register. This can be parameterised during the IP instantiation and is often left as '0x00000000' which is not an error.

To connect two ports of the same configuration (MDI to MDI or MDI-X to MDI-X) with a 10/100/1000 Mbit/s connection, an Ethernet crossover cable is needed to cross over the transmit and receive signals in the cable, so that they are matched at the connector level. When connecting an MDI port to an MDI-X port a straight through cable is used while to connect two MDI ports or two MDI-X ports a crossover cable must be used. Conventionally MDI is used on end devices while MDI-X is used on hubs and switches Auto MDI-X automatically detects the required cable connection type and configures the connection appropriately, removing the need for crossover cables to interconnect switches or connecting PCs peer-to-peer.

This is a test to verify that bpf: fix states equal logic for varlen access actually fixed the problem. The problem was if the register we added to our map register was UNKNOWN in both the false and true branches and the only thing that changed was the range then we'd incorrectly assume that the true branch was valid, which it really wasnt. This tests this case and properly fails without my fix in place and passes with it in place. Signed-off-by:

The cpdma has 8 rate limited tx channels. This patch adds ability for cpdma driver to use 8 tx h/w shapers. If at least one channel is not rate limited then it must have higher number, this is because the rate limited channels have to have higher priority then not rate limited channels. The channel priority is set in low-hi direction already, so that when a new channel is added with ethtool and it doesn't have rate yet, it cannot affect on rate limited channels. It can be useful for TSN streams and just in cases when h/w rate limited channels are needed. Signed-off-by:

Patches #1, #2, #8, #9 belong to this group. - Refactoring - done mostly in favour of XDP. Patches #3, #4, #5, #9. - Infrastructure changes - done in favour of XDP.

Add support for forwarding via XDP. Once the eBPF is attached, driver would allocate & configure a designated transmission queue meant solely for forwarding packets. Said queue would share the receive-queue's interrupt line, and would have it's own Tx statistics. Infrastructure changes required for this [spread-out through the code]: - Determine the DMA direction of the receive buffers based on the presence of the eBPF program. - Turn the sw Tx ring into a union, as regular/XDP queues have different needs for releasing resources after completion [regular requires the SKB, XDP requires the transmitted page].

The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.
