igc: Add PHY power management control

2020-01-17T17:55:34Z

PHY power management control should provide a reliable and accurate indication of PHY reset completion and decrease the delay time after a PHY reset Signed-off-by: Sasha Neftin Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Add support for TSO

2020-01-17T17:55:34Z

TCP segmentation offload allows a device to segment a single frame into multiple frames with a data payload size specified in socket buffer. As a result we can now send data approximately up to seven percents fast than was previously possible on my system. Signed-off-by: Sasha Neftin Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Add SKU for i225 device

2020-01-17T17:55:34Z

Add support for blank NVM SKU Signed-off-by: Sasha Neftin Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Remove unused definition

2020-01-17T17:55:34Z

Remove the unused IGC_FUNC_0 definition and make the code cleaner Signed-off-by: Sasha Neftin Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Fix typo in a comment

igc: Use Start of Packet signal from PHY for timestamping

2020-01-06T23:02:45Z

For better accuracy, i225 is able to do timestamping using the Start of Packet signal from the PHY. Signed-off-by: Vinicius Costa Gomes Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Add support for ethtool GET_TS_INFO command

2020-01-06T22:59:48Z

This command allows igc to report what types of timestamping are supported. ptp4l uses this to detect if the hardware supports timestamping. Signed-off-by: Vinicius Costa Gomes Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher

igc: Add support for TX timestamping

2020-01-06T22:39:17Z

This adds support for timestamping packets being transmitted. Based on the code from i210. The basic differences is that i225 has 4 registers to store the transmit timestamps (i210 has one). Right now, we only support retrieving from one register, support for using the other registers will be added later.

igc: Add support for RX timestamping

2020-01-06T22:19:31Z

This adds support for timestamping received packets. It is based on the i210, as many features of i225 work the same way. The main difference from i210 is that i225 has support for choosing the timer register to use when timestamping packets. Right now, we only support using timer 0. The other difference is that i225 stores two timestamps in the receive descriptor, right now, we only retrieve one.

igc: Add basic skeleton for PTP

2020-01-06T21:33:01Z

This allows the creation of the /dev/ptpX device for i225, and reading and writing the time. Signed-off-by: Vinicius Costa Gomes Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher
