[PATCH 01/21] e1000: Split driver into multiple files

Andrey Smirnov andrew.smirnov at gmail.com
Tue May 31 10:09:20 PDT 2016


The driver has a number of not very tightly coupled subsystems and at
4K+ lines e1000.c is getting rather hard to wrangle, so let's move
EEPROM handling code (very self contained susbsystem) into a separate
file and put all of the driver into a dedicated subdirectory.
