On Fortville NIC, link status change interrupt callback is not executed when
slave in bonding is (re-)started. It causes that slave's NIC is inactive even
if its link status is up on the start.
This patch invokes lsc callback, just after port's start, to check its initial
link status and manage properly.

This patch adds max_link_up_time parameter to mac structure.
This parameter is used to control maximum link polling time in
ixgbe_check_mac_link functions. It is required to prevent long wait
time on x550 PHY that have no external link.
Since x550 is handled by software, we have to reset internal (PHY to
PHY) link when external link changes, and after reset, we have to wait for
this link to be established. As a result of not having interrupts, we have
to poll for link state, and we know that this link comes up much faster
than default 9 seconds. This parameter is added to prevent waiting 9
seconds for link when external link is not established.

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.
