       See also Net::Frame::Layer for other attributes and methods.

newnew (hash)
           Object  constructor.  You  can  pass  attributes  that  will overwrite default ones. See SYNOPSIS for
           default values.

       getKeygetKeyReverse
           These  two  methods  are  basically  used  to  increase  the  speed  when  using  recv  method   from
           Net::Frame::Simple. Usually, you write them when you need to write match method.

       match (Net::Frame::Layer::ARP object)
           This method is mostly used internally. You pass a Net::Frame::Layer::ARP layer as a parameter, and it
           returns true if this is a response corresponding for the request, or returns false if not.

       The  following  are  inherited methods. Some of them may be overridden in this layer, and some others may
       not be meaningful in this layer. See Net::Frame::Layer for more information.
