 # == Define: iface::dhcp
 #
 # Resource to define an interface configuration stanza within interfaces(5).
 #
 # == Parameters
 #
 # [*ifname*] => *(namevar)* - string
 #   Name of the interface to be configured.
 #
 # [*method*] - string
 #   Configuration method to be used.
 #
 # [*auto*] - bool
 #   Sets the interface on automatic setup on startup. This is affected by
 #   ifup -a and ifdown -a commands.
 #
 # [*allows*] - array
 #   Adds an allow- entry to the interface stanza.
 #
 # [*family*] - string
 #   Address family. Currently, only inet family is supported. Support for
 #   inet6 is comming soon.
 #
 # [*order*] - int
 #   Order of the entry to be created in /etc/network/interfaces. Innate
 #   odering is preset with default value of 10 for loopback and 20 for dhcp
 #   and static stanzas. The order attribute of the resource is added to the
 #   default value.
 #
 # [*hwaddress*] - string
 #   The MAC address of the interface. This value is validated as standard
 #   IEEE MAC address of 6 bytes, written hexadecimal, delimited with
 #   colons (:) or dashes (-).
 #
 # [*hostname*] - string
 #   The hostname to be submitted with dhcp requests.
 #
 # [*leasetime*] - int
 #   The requested leasetime of dhcp leases.
 #
 # [*vendor*] - string
 #   The vendor id to be submitted with dhcp requests.
 #
 # [*client*] - string
 #  The client id to be submitted with dhcp requests.
 #
 # [*metric*] - int
 #  Routing metric for routes added resolved on this interface.
 #
 # [*pre_ups*] - array
 #  Array of commands to be run prior to bringing this interface up.
 #
 # [*ups*] - array
 #  Array of commands to be run after bringing this interface up.
 #
 # [*downs*] - array
 #  Array of commands to be run prior to bringing this interface down.
 #
 # [*post_downs*] - array
 #  Array of commands to be run after bringing this interface down.
 #
 # [*aux_ops*] - hash
 #  Hash of key-value pairs with auxiliary options for this interface.
 #  To be used by other debnet types only.
 #
 # [*tx_queue*] - int
 #  Feature helper for setting tx queue on the interface.
 #
 # [*routes*] - hash
 #  Feature helper for setting static routes via the interface.
 #
 # [*dns_nameserver*] - array
 #  Feature helper to add a list of nameservers to be configures via resolvconf
 #  while the interface is set up.
 #
 # [*dns_search*] - array
 #  Feature helper to add a list of domain names as dns search via resolvconf
 #  while the interface is set up.
