Net::Frame::Layer::ETH - Ethernet/802.3 layer object

srcdst Source and destination MAC addresses, in classical format (00:11:22:33:44:55).

       type
           The encapsulated layer type (IPv4, IPv6 ...) for Ethernet. Values for Ethernet types are greater than
           1500.    If    it    is   less   than   1500   the   layer   is   considered   a   802.3   one.   See
           http://www.iana.org/assignments/ethernet-numbers .

       length
           The length of the payload when this layer is a 802.3 one. This is the same attribute as type, but you
           cannot use it when calling new (you can only use it as an accessor after that).

       The following are inherited attributes. See Net::Frame::Layer for more information.

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

       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.
