am1808/lan8710a auto-negotiation timeout

Hi I got a board with AM1808, SMSC LAN8710A and HY951180A.

Board works fine if booted with ethernet cable connected.

Link detection and auto-negotiation work fine if ethernet cable it removed for less than 10 seconds and reconnected.

However if ethernet cable is removed for longer than 10 seconds and reconnected, link is not reestablished.

Time threshold is 10s with one switch and smth like 15s with another switch.

I can work around the problem from command line:
ethtool -s eth0 autoneg off; ethtool -s eth0 autoneg on

sw is DaVinci-PSP-SDK-03.21.00.04, linux-03.21.00.04 with some patches, arch linux.

Any idea what could be wrong with the board or driver?

What should I check first?

Thanks.
