Subject: [PATCH v2] net: phy: wait for link OK after successfull autonegotiation
Date: Wed,  4 Nov 2015 22:23:04 +0100	[thread overview]
Message-ID: <1446672184-15215-1-git-send-email-anton.bondarenko.sama@gmail.com> (raw)

It may take some time for PHY to indicate link OK status after
autonegotiation completed. This change addresses this case
and prevent network commands fails due to the delay.
