From: Kai-Heng Feng kai.heng.feng@canonical.com
[ Upstream commit afb133637071be6deeb8b3d0e55593ffbf63c527 ]
The sky2 ethernet stops working after system resume from suspend: [ 582.852065] sky2 0000:04:00.0: Refused to change power state, currently in D3
The current 150ms delay is not enough, change it to 200ms can solve the issue.
