Jon Mason authored
Add support for the variant of amac hardware present in the Broadcom Northstar2 based SoCs. Northstar2 requires an additional register to be configured with the port speed/duplexity (NICPM). This can be added to the link callback to hide it from the instances that do not use this. Also, clearing of the pending interrupts on init is required due to observed issues on some platforms.

The BCM54810 PHY requires some semi-unique configuration, which results in some additional configuration in addition to the standard config. Also, some users of the BCM54810 require the PHY lanes to be swapped. Since there is no way to detect this, add a device tree query to see if it is applicable.

Joachim Eastwood says: ==================== stmmac: dwmac-sti refactor+cleanup This patch set aims to remove the init/exit callbacks from the dwmac-sti driver and instead use standard PM callbacks. Doing this will also allow us to cleanup the driver. Eventually the init/exit callbacks will be deprecated and removed from all drivers dwmac-* except for dwmac-generic. Drivers will be refactored to use standard PM and remove callbacks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-11-04 This series contains updates to ixgbe and ixgbevf only. Don does cleanup and configuration for our X553 devices, related to LED, auto-negotiation, flow control and SFP+ setup and config. Adds the (not secret) sauce for B0 hardware for X553 hardware. Emil provides several fixes, first replaces the driver specific MDIO defines for the more preferred equivalent kernel ones. Provides a fix for auto-negotiaion status, by reading a PHY register twice. Introduces ixgbe_link_operations structure to allow X550EM_a to override the methods for MDIO access while X550EM_x provides methods to use I2C combined access. Mark fixes an issue where the driver was crashing when msix_entires were not there because they were freed by a previous suspend or remove. Sowmini Varadhan fixes an issue where an incorrect check for IPPROTO_UDP in ixgbe_atr(). Then makes sure that the network and transport headers in the paged data are available in the headlen bytes to calculate the l4_proto. ==================== Signed-off-by: David S.

Sowmini Varadhan authored
For some Tx paths (e.g., tpacket_snd()), ixgbe_atr may be passed down an sk_buff that has the network and transport header in the paged data, so it needs to make sure these headers are available in the headlen bytes to calculate the l4_proto. This patch expect that network and transport headers are already available in the non-paged header dat. The assumption is that the caller has set this up if l4_proto based Tx steering is desired.

Introduce ixgbe_link_operations struct with the following changes: read_i2c_combined => read_link read_i2c_combined_unlocked => read_link_unlocked write_i2c_combined => write_link write_i2c_combined_unlocked => write_link_unlocked This will allow X550EM_a to override these methods for MDIO access while X550EM_x provides methods to use I2C combined access. This also adds a new structure, ixgbe_link_info, to hold information about the link. Initially this is just method pointers and a bus address. The functions involved in combined I2C accesses were moved from ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry out the combined I2C accesses were left in ixgbe_phy.c because they share some functions with other I2C methods. v2 - set hw->link.ops in probe. v3 - check ii->link_ops before setting it since we don't have it for all devices.

Jakub Kicinski says: ==================== ring reconfiguration and XDP support This set adds support for ethtool channel API and XDP. I kick off with ethtool get_channels() implementation. set_channels() needs some preparations to get right. I follow the prepare/commit paradigm and allocate all resources before stopping the device. It has already been done for ndo_change_mtu and ethtool set_ringparam(), it makes sense now to consolidate all the required logic in one place. XDP support requires splitting TX rings into two classes - for the stack and for XDP. The ring structures are identical. The differences are in how they are connected to IRQ vector structs and how the completion/cleanup works. When XDP is enabled I switch from the frag allocator to page-per-packet and map buffers BIDIRECTIONALly. Last but not least XDP offload is added (the patch just takes care of the small formal differences between cls_bpf and XDP). There is a tiny & trivial DebugFS patch in the mix, I hope it can be taken via net-next provided we have the right Acks. Resending with improved commit message and CCing more people on patch 10. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
