Add EEE TX LPI and EEE RX LPI counters. A EEE TX LPI event occurs when the transmitter enters EEE (IEEE 802.3az) LPI state.

2020-06-29igc: Clean up Rx timestamping logicAndre Guedes1-2/+0
Differently from I210, I225 doesn't report Rx timestamps via the TS bit Rx descriptor + RXSTMPL/RXSTMPH registers mechanism. Rx timestamps are reported in the packet buffer only, which is implemented by igc_ptp_rx_ pktstamp(). So this patch removes igc_ptp_rx_rgtstamp() and all code related to it, copied from igb driver.

2020-04-17igc: Add support for taprio offloadingVinicius Costa Gomes1-0/+12
Adds support for translating taprio schedules into i225 cycles. This will allow schedules to run in the hardware, making the schedules enforcement more precise and saving CPU time. Right now, the only simple schedules are allowed, complex schedules are rejected. "simple" in this context are schedules that each HW queue is opened and closed only once in each cycle. Changing schedules is still not supported as well.

2020-01-06igc: Add support for RX timestampingVinicius Costa Gomes1-0/+3
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.
