AppleIntelE1000e.kext 32/64 for 10.8,10.7,10.6 & 10.5 (until 2.0.0).
This driver is based on Intel Wired Ethernet for Linux ( e1000.sourceforge.net ) . As it uses ( almost as is ) Linux driver's source code, the license is GPL.
The base Linux driver is e1000e-1.9.5 and works with Intel PCI Express ethernet chips like 82578 (P55/H55) and 82579 (P67/H67).
I tested 82573, 82574L, 82578, 82579 only as I do not have other NICs.
82575/82578/82580 based NIC needs another one - AppleIGB.kext.
List of the IDs supported by original driver:
0x104B and 0x10F6 are supported by Apple's Intel82574L.kext ( so removed from this driver's Info.plist ).
Availabie at: sourceforge .
