Subject: [PATCH] Improve PHY AutoNeg procedure
Date: Sat, 31 Oct 2015 14:07:51 +0100 [thread overview]
Message-ID: <1446296872-1592-1-git-send-email-anton.bondarenko.sama@gmail.com> (raw)
While working with IMX6Q Embedsky E9 I've noticed the problem with
first attempt to run 'ifup eth0'. The root cause of the failure is in PHY
not setting bit '1.2 Link Status' at the same time as setting
bit '1.5 Auto-Negotiation Complete'. The delay between these changes
could be up to 4 ms. PHY is Realtek RTL8211E. The proposed change would
improve handling of similar situations.
