It's more valuable to abstract the link read/write interface. As such,

read_i2c_combined => read_link
read_i2c_combined_unlocked => read_link_unlocked
write_i2c_combined => write_link

This will allow X550EM_a to override these methods for MDIO access

Initially the structure is just method pointers and a bus

Two functions involved in combined I2C accesses were moved from

Eventually, we decided that there is no harm in having SW do

EEE(Energy Efficient Ethernet) is not supported on the initial revision
of IXGBE_DEV_ID_X550EM_X_KR. We determine the revision by reading a fuse
register.
Also, the requirements for FEC(Forward Error Correction) have changed
slightly. Now, we don't change the "request" bit at all. When EEE is
enabled, we advertise that we are capable. When EEE is disabled, we do
not advertise that we are capable. This change makes us consistent with
the power-on defaults that are in the NVM.

The FEC(Forward Error Correction) feature had been disabled
because it increases power consumption. However, some customers
want to use it. This patch enables FEC when EEE(Energy Efficient
Ethernet) is disabled; FEC was already being disabled when EEE
was enabled, but now both are done in the same function. The two
features are not allowed to be enabled at the same time. The two
features cannot both be disabled. If this ability is ever
determined to be needed, we will need to define a new user parameter
to control FEC independently of EEE.

The init flow is simplified. We no longer wait for the PHY FW init
complete bit to be set as this bit is only set once by the PHY at power
on and then cleared on the first read. So only the first instance of
running SW (or possibly MAC FW) needs to initialize the PHY.
The PHY initialization has been simplified and now only requires that
the PHY FW be "un-stalled". SW no longer needs to put the PHY in
low-power mode or enable the transceiver.
