Дрова marvell, смена страниц в протоколе обмена присутствует (наблюдал вживую), прерывания в PHY инициализируются и работают (после срабатывания прерывания идет общение mac-phy по mdio).

тогда ищите, где пропадает инфа для МАСа, при выдергивание меди из 1512 в логе д.б. примерно так:

# [  352.422375] stmmaceth ff702000.ethernet eth0: Link is Down
[  357.422707] stmmaceth ff702000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off

а вот так выглядит отчет по 1512 с поддержкой медь-оптика в режиме медь:

# ethtool gbe0
