After setting up the link on x552/X557-AT 10GBASE-T NICs, sometimes the
link does not get set up properly and as a result all the subsequent
calls to ixgbe_check_link() from ixgbe_dev_link_update_share() fail.
Introduce a delay time of 1s in ixgbe_setup_mac_link_t_X550em() before
beginning to set up the external PHY link speed to ensure that the
controller can acquire the link.

Hello,
This patch makes changes in the base driver.
Similar patch was introduced in case of fiber link MAC setup earlier
