inside the ring buffer and using (N-1) mask instead. This patch fixes omission

Also, list here, what has changed since v1.

IEEE802.3az-2010 Energy Efficient Ethernet has been
approved as standard (September 2010) and the driver
can enable and disable it via ethtool.
Disable the feature by default on parts which support it.
Add enable/disable eee options.
tx-lpi, tx-timer and advertise not supported
From: Sasha Neftin
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. A EEE RX LPI event occurs when the receiver detect
link partner entry into EEE(IEEE 802.3az) LPI state.

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

As implemented in igc_ethtool_get_ts_info(), igc only supports HWTSTAMP_
FILTER_ALL so any HWTSTAMP_FILTER_* option the user may set falls back to
HWTSTAMP_FILTER_ALL.
HWTSTAMP_FILTER_ALL is implemented via Rx Time Sync Control (TSYNCRXCTL)
configuration which timestamps all i

Currently the implementation of igc_power_down_link()
method was just calling igc_power_down_phy_copper_base()
method.
We can just call igc_power_down_phy_copper_base()
method directly.

Current igc_ptp_set_timestamp_mode() logic is a bit tangled since it
handles many different hardware configurations in one single place,
making it harder to follow. This patch untangles that code by breaking
it into helper functions.

The __IGC_PTP_TX_IN_PROGRESS flag indicates we have a pending Tx
timestamp. In some places, instead of checking that flag, we check
adapter->ptp_tx_skb. This patch fixes those places to use the flag.

The functions igc_ptp_tx_hang() and igc_ptp_tx_work() have duplicate
code which handles Tx timestamp timeouts. This patch does a trivial
refactoring by moving that code to its own function and reusing it.

When Rx timestamping is enabled, we set the timestamp bit in SRRCTL
register for each queue, but we don't clear it when disabling. This
patch fixes igc_ptp_disable_rx_timestamp() accordingly.
Also, this patch gets rid of igc_ptp_enable_tstamp_rxqueue() and
