ixgbe: Fix 82598 premature copper PHY link indicatation

Browse source

Modified patch with Dave's comments to replace mdelay with proper msleep.
Fix 82598 copper link issue, where the phy prematurely indicates link
before it is ready to process packets. The new function looks for phy
link and indicates that, when it is available. If phy is not ready
within few seconds of MAC indicating link, the function will return
failure which translates to link down indication.
