You have too many Ethernet kexts:
AtherosE2200Ethernet
IntelMausi
RealtekRTL8100
RealtekRTL8111
SmallTreeIntel82576
Determine what actual Ethernet on the system and remove the rest.
However that's not the culprit, it's power management you should look for. You have NullCPUPowerManagement.kext. The name itself should have given you a clue.
Remove that kext and VoodooTSCSync.kext( for desktop usually).
Still not knowing your system's spec and Config file attached, we have no clue to assist.
If Haswell and above, you could simple enable PluginType or create SSDT.aml with well known ssdtPRGen.sh script
If IvyBridge / SandyBridge, you'll need to enable AppleIntelCPUPM in the Config file with CC
Also if you have dual graphics and the discrete graphics is not disable (not supported), it'll drain your battery as well.
