Thanks for fixing the variable name. But don't you think it would of
made sense to rename DM9051_PHY_ID as well? DM9051_PHY_ADDR?

pause->autoneg means that pause is negotiated as part of autoneg in
general. But pause->autoneg does not mean turn on autoneg. The
ksetting calls should be used for that.

If pause->autoneg is false, you write the pause settings direct to the
MAC. If it is true, you should call phy_set_sym_pause(). Once
negotiation has completed the link change callback will be called, and
you program the MAC with what has been negotiated.
