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.

During init, check the ucode running in the CS4227. If
it is not responding correctly, reset the part. This is
a global reset so it must only be done the first time a
driver loads after power-on.

In UniPHY we have 2 IOSF targets that are UniPHY related. We can
write to PHY and PCS. In earlier times I've been told that there
were 2 separate PCS targets for IOSF commands and that's why I
implemented it with 2 defines and adding hw->bus.lan_id, but lately
I confirmed with HW that FW takes care of which PCS "slice" we are
talking to and is directing writes to correct one, so KX4_PCS1
target is dead now and we cannot use it.

This patch powers down the x550em PHY on over-temp events. The
PHY firmware is supposed to do this autonomously but that isn't
implemented. The short-term stop-gap solution is for SW to power
down the PHY when it reports an overtemp event.

Configure the CS4227 correctly for both 1G and 10G operation,
by moving the code to ixgbe_setup_mac_link_sfp_x550em(). It
needs to be in this function because we need both the module
type and the speed, and this is the only function in the init
flow that knows the speed. In contrast,
ixgbe_setup_sfp_modules_X550em() does not know the speed, so we
can't do anything useful here. This is a fundamental difference
from the 82599 flow.

architectures will need to define CONFIG_RTE_ARCH_STRICT_ALIGN in
