############################
# Special Interface Handling
############################
# If the interface requires the running of a daemon or configuration program
# two functions must be supplied taking the interface name as the first
# and only argument.  Both of these functions have names of the form
# <if-name|if-type>_start and <if-name|iftype>_stop, with the former
# starting the interface and the latter shutting it down and deconfiguring it.
# The following global variables will be set for the <if-namei|if-type>_start
# function if they are configured.
#
# IPADDR          - interface IP address/mask -OR- the new form as above
# BROADCAST       - interface broadcast address
# PTPADDR         - PTP address of interface
# IP_EXTRA_ADDRS  - Extra IP addesses/networks bound to interface
#
# The if_addr_start function in if.conf should be used to set the addresses on
# the interface once it is created.  It also sets the interface sysctl 
# /proc flags, and brings the interface up, as well as enabling the use 
# of multiple addresses on the interface. The if_addr_stop compleimentary 
# function should be used to down the itnerface and clear the addresses off it.
#
# BOTH A START AND A STOP FUNCTIONS SHOULD PROBABLY DEFINED if you use them.
#
# The if-type of an interface name is given by the first alpha-numerics
# of the name excluding the instance number on the end - ie the type of "eth1"
# is "eth" and the type of "wan1a2" is "wan1a".
#
# The code in if.conf first of checks for an individual interface function,
# then a typed interface function, and then uses the default which is for
# ethernet type interfaces
#
# If you are starting a tunneling interface that is dependent on another
# interface being up to continue to function correctly, use the intX_IF_CHAIN
# and intX_IF_CHAIN_AUTO interface variables for the hardware interfaces to
# start and stop the tunneled interfaces.  Also add the tunnel interface to 
# IF_AUTO AFTER the hardware interface so that it is started on boot.
#
# Static routes and other network setup can be handled by using the 
# <if-name>_network functions or those above, but the recomendation is to 
# run the zebra routing daemons as this has problems with clearing
# unwanted routes etc.
#
# Here are some example functions, some of which are actually used
#
# PPP - interface ppp0
