6.1-stable review patch. If anyone has any objections, please let me know.

From: Jose Ignacio Tornos Martinez jtornosm@redhat.com
commit 058722ee350c0bdd664e467156feb2bf5d9cc271 upstream.
Avoid spurious link status logs that may ultimately be wrong; for example, if the link is set to down with the cable plugged, then the cable is unplugged and after this the link is set to up, the last new log that is appearing is incorrectly telling that the link is up.
In order to avoid errors, show link status logs after link_reset processing, and in order to avoid spurious as much as possible, only show the link loss when some link status change is detected.
