3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Benjamin Poirier <[email protected]> commit 4e7dc08e57c95673d2edaba8983c3de4dd1f65f5 upstream. When autoneg is off, the .check_for_link callback functions clear the get_link_status flag and systematically return a "pseudo-error". This means that the link is not detected as up until the next execution of the e1000_watchdog_task() 2 seconds later.
