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.

2016-11-04ixgbe: ixgbe_atr() compute l4_proto only if non-paged data has network/transport headersSowmini Varadhan1-0/+17
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.

2016-11-04ixgbe: use link instead of I2C combined abstractionEmil Tantilov5-90/+124
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.

While the two bits for link, duplex or RGMII delays are used the same way on chips supporting the said feature, the two bits for speed have different meaning for most of the chips out there. Speed value is stored in bits 1:0, 0x3 means unforce (normal detection). Some chips reuse values for alternative speeds when bit 12 is set. Newer chips with speed > 1Gbps reuse value 0x3 thus need a new bit 13. Here are the values to write in register 0x1 to (un)force speed: | Speed | 88E6065 | 88E6185 | 88E6352 | 88E6390 | 88E6390X | | ------- | ------- | ------- | ------- | ------- | -------- | | 10 | 0x0000 | 0x0000 | 0x0000 | 0x2000 | 0x2000 | | 100 | 0x0001 | 0x0001 | 0x0001 | 0x2001 | 0x2001 | | 200 | 0x0002 | NA | 0x1001 | 0x3001 | 0x3001 | | 1000 | NA | 0x0002 | 0x0002 | 0x2002 | 0x2002 | | 2500 | NA | NA | NA | 0x3003 | 0x3003 | | 10000 | NA | NA | NA | NA | 0x2003 | | unforce | 0x0003 | 0x0003 | 0x0003 | 0x0000 | 0x0000 | This patch implements a generic mv88e6xxx_port_set_speed() function used by chip-specific wrappers to filter supported ports and speeds.
