Committed By: tsutsui
Date: Mon Sep 17 11:54:36 UTC 2012
Modified Files:
src/sys/dev/pci: if_bge.c if_bgereg.h
Log Message:
Add support for BCM57762, found in Apple's Thunderbolt to Gigabit Ethernet
Adapter. PR kern/46961 from Ryo ONODERA.
Also revert weird BGE_MAX_FRAMELEN macro definition to sync its usage
with the original FreeBSD's bge.
