igc: Expose LPI counters
Completion to commit 900d1e8b346b ("igc: Add LPI counters") LPI counters exposed by statistics update method. A EEE TX LPI counter reflect the transmitter entries EEE (IEEE 802.3az) into the LPI state. A EEE RX LPI counter reflect the receiver link partner entries into EEE(IEEE 802.3az) LPI state.
