# Network DSC include file for [Defines] section of all Architectures.

# This file can be included to the [Defines] section of a platform DSC file by
# using "!include NetworkPkg/NetworkDefines.dsc.inc" to set default value of
# flags if they are not defined somewhere else, and also check the value to see
# if there is any conflict.
#
# These flags can be defined before the !include line, or changed on the command
# line to enable or disable related feature support.
#   -D FLAG=VALUE
# The default value of these flags are:

  #       set to FALSE, MD5 is disabled statically, at build time.
