The I2C interface was not being correctly locked down per port.  As such
this can lead to race conditions that can cause issues.  This patch cleans
up the handling to make certain we are not experiencing racy I2C access.

We were reading the address after it had been initialized and this results
in the permanent address on the system being changed.  This change corrects
that by storing the address before we re-initialize it.

This change modifies the ixgbe drivers so that it will not drop the

The X540 PHY reset pointer isn't currently used which is a good thing as it
wouldn't work as implemented.  On top of that the X540 firmware is written
with the assumption that is does not need to be reset for proper
initialization so it's not needed.  I'm just assigning the pointer at NULL
as the current implementation is rather misleading.

Currently check link reports the link state as down, if at any time
the link had previously gone down since the last time the LINKS
register was read.  This does not accurately reflect the function of
the check link call, which should be to return the CURRENT link
state. Code now reads the LINKS registers twice, once to clear the
previous and again to get the current value.

Double resets are required for recovery from certain error conditions.
Between resets, it is necessary to stall to allow time for any pending HW
events to complete. We use 1usec since that is what is needed for
ixgbe_disable_pcie_master(). The second reset then clears out any effects
of those events.
