Please express this using
/* 1000BASE-T Control register */
#define ADVERTISE_1000FULL 0x0200 /* Advertise 1000BASE-T full duplex */
#define ADVERTISE_1000HALF 0x0100 /* Advertise 1000BASE-T half duplex */
#define CTL1000_PREFER_MASTER 0x0400 /* prefer to operate as master */
#define CTL1000_AS_MASTER 0x0800
#define CTL1000_ENABLE_MASTER 0x1000
Once we have symbolic names, it might be obvious what this is doing,
and if there is a better way to do it.

Any idea why? Is EEE broken? If it is, phy_disable_eee().
