Because there is no publicly available data sheet for Atheros F1
PHY I'm not sure what could be done in this case.  The only thing
I can think of at this moment is announcement of next page in auto
negotiation.  atphy(4) does not directly manipulate master/slave,
single port/multi port configuration and this configuration may
need next page if other link partner also announces next page
capability.
Try attached patch and let me know whether this makes any
difference for you.  You may have to cold boot the box because
stock driver used to clear next page bit in auto-negotiation.
