DEVICE=<name>

[ BOOTPRIO=number ]
  ifcfg-* interfaces are configured in BOOTPRIO order starting
  from lowest value first. You need to set BOOTPRIO in _all_ your
  ifcfg* files because if you won't do that only these interfaces
  with BOOTPRIO variable will be configured. Use the same schema
  when setting variable for example BOOTPRIO=number
  or BOOTPRIO="number" because sorting is done by sort command.

[ BOOTPROTO={none|bootp|dhcp|pump} ]
  You can specify which dhcp client to use with the DHCP_CLIENT, if
  the DHCP_CLIENT is not specified we trying to launch in order :
  /sbin/dhcpcd
  /sbin/dhclient
  /sbin/dhcpxd
  /sbin/pump
  if you have a preferred client define the DHCP_CLIENT variable.
  You can also pass some options to dhcp client via DHCP_OPTIONS.

[ BOOTPROTO6={none|dhcp6|v4compat}
  dhcp6 isn't supported, yet.
  v4compat uses available IPv4 addresses (ie. from DHCPv4)
  and then convert them to IPv6 (IPv4-compatible) to use with
  automatic tunnels


IPADDR="(IPv4 or IPv6 address)/prefix"
IP_AOPTS="broadcast xxx etc" (by default broadcast is autocalculated)
IP_ROPTS=""
IP_LABEL=""

IPADDR1=
IP_AOPTS1= options for ip addr add
IP_ROPTS1= options for ip route add (currently used only for IP4_PRIM_IF)
IP_LABEL1= IPv6 address label as per RFC 3484 (ip addrlabel ...)

IP4_PRIM_IF="1"		# number of primary IPv4 interface (IPADDRx)
IP4_SRC_IF="1"		# number of IPv4 address for ip's ,,src'' parameter
IP6_PRIM_IF=""		#

[ ONBOOT={no|yes} ]
[ HOTPLUG={no|yes} ] - bring up from hotplug (udev for example) (default to no)
[ MULTICAST={|no|yes} ]	- for eth automatically set to yes
[ ARP={no|yes} ]	- for eth automatically set to yes
[ IPV6_DISABLE_AUTOCONF={yes|no} ] - disable IPv6 autoconfiguration

                                then tbf is used)
BANDWIDTH_IN=[upstream limit in kilobites, supported on 2.4 only]
BANDWIDTH_OUT=[downstream limit in kilobites]

VLAN_REORDER_HDR=[0|1]	When this is set, the VLAN device will move the
			ethernet header around to make it look exactly like a
			real ethernet device.  This may help programs such
			as DHCPd which read the raw ethernet packet and
			make assumptions about the location of bytes.
			If you don't need it, don't turn it on, because there
			will be at least a small performance degradation.
			Default is ON.
