# A patch to add complete support for the BIOCSHDRCMPLT ioctl to Mac OS X 
# Panther (Darwin).  This is also known as ETHERSPOOF.
# 
# This patch improves the functionality provided in the ETHERSPOOF patch
# by Peter Bartoli.  NOTE: This patch is incompatible with the ETHERSPOOF patch.
#
# Instead of (potentially) altering the source Ethernet address of all 
# AF_UNSPEC packets, this patch only affects packets when the BIOCSHDRCMPLT 
# ioctl is used.  In other words, this won't break dhcp.
#
# apply in the top level xnu-xxx source directory:
# patch -p0 -b --verbose --suffix=.orig < BIOCSHDRCMPLT-panther.patch
#
# Then, build the kernel and install it as you normally would.
