Default value (4000ms) of PHY_ANEG_TIMEOUT for Micrel KSZ9031 contoller isn't sufficient to finish auto-negotiation, which sometimes leads to timeout errors:
Apalis iMX6 # dhcp FEC Waiting for PHY auto negotiation to complete......... TIMEOUT !
Increase the auto-negotiation time-out to 8000ms.
Hi Igor, I did a lot of auto-negotiation tests with this PHY. It can happen, that it has up to 12s for a connection with some partners. So I'd suggest to put that timeout up to 15s to cover most situations.
