The MAC-PHY interconnect on 82577/82578 uses a power management feature (called K1) which must be disabled when in 1Gbps due to a hardware issue on these parts. The #define bit setting used to enable/disable K1 is incorrect and can cause PHY register accesses to stop working altogether until the next device reset. This patch sets the register correctly. This issue is present in kernels since 2.6.32.
