Module Name: src
Committed By: msaitoh
Date: Sat May 16 22:41:59 UTC 2015
Modified Files:
src/sys/dev/pci: if_wm.c if_wmreg.h if_wmvar.h
Log Message:
Add support iNVM (integrated Non-Volatile Memory) for I21[01]. This change
fixes a bug that a MAC address is wrongly set on iNVM machines and NICs.
Tested with Shuttle DS57U(iNVM based) and other non iNVM based I210 machines.
