Hi,

Continuing on with the STMMAC EEE cleanups from last cycle, this series
further cleans up the EEE code, and fixes a problem with the existing
implementation - disabling EEE doesn't immediately disable LPI
signalling until the next packet is transmitted. It likely also fixes
a potential race condition when trying to disable LPI vs the software
timer.
