[Intel-wired-lan] [PATCH S39 v2 10/15] ice: Don't tell the OS that link is going down

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Michal Swiatkowski <michal.swiatkowski@intel.com>

Remove code that tell the OS that link is going down when user
change flow control via ethtool. When link is up it isn't certain
that link goes down after 0x0605 aq command. If link doesn't go
down, OS thinks that link is down, but physical link is up. To
reset this state user have to take interface down and up.

If link goes down after 0x0605 command, FW send information
about that and after that driver tells the OS that the link goes
down. So this code in ethtool is unnecessary.
