Subject: phylib: Any PHY which reports link up during autoneg ?
Date: Thu, 16 Aug 2018 21:15:47 +0200	[thread overview]
Message-ID: <9996748f-c274-e1de-6a5a-962f2035d5c2@gmail.com> (raw)

When reading through the state machine code in phy.c I wondered whether
there is any PHY which reports the link as up during autonegotiation.
(It's about handling PHY_AN in the state machine, once we know the link
is up we still check whether aneg was completed. Is this needed?)

At least the PHY's I have access to all report the link as down when
autonegotiating.
I checked also clause 22 of 802.3u, however found no clear definition
when a link should be considered up. There it's stated that it's
PHY-dependent.

Can you shed any light on this?

Thanks, Heiner
