It seems that mii_ticks is not kicked at all in auto-negotiation
phase. From the output of forced 1000baseSX media configuration I
guess BRGPHY_BMSR_ACOMP bit in BRGPHY_MII_BMSR is not updated on
5708S. Mabe davidch know better what's going on 5708S. (CCed)
How about attached patch? I don't have the hardware so it's just a
guess work.
