NAME

       Net::Frame::Layer::SLL - Linux cooked capture layer object

SYNOPSIS

          use Net::Frame::Layer::SLL qw(:consts);

          # Build a layer
          my $layer = Net::Frame::Layer::SLL->new(
             packetType    => NF_SLL_PACKET_TYPE_SENT_BY_US,
             addressType   => NF_SLL_ADDRESS_TYPE_512,
             addressLength => 0,
             source        => 0,
             protocol      => NF_SLL_PROTOCOL_IPv4,
          );
          $layer->pack;

          print 'RAW: '.$layer->dump."\n";

          # Read a raw layer
          my $layer = Net::Frame::Layer::SLL->new(raw => $raw);

          print $layer->print."\n";
          print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"

DESCRIPTION

       This modules implements the encoding and decoding of the Linux cooked capture layer.

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

ATTRIBUTES

       packetType
           Stores the packet type (unicast to us, sent by us ...).

       addressType
           The address type.

       addressLength
           The length of the previously specified address.

       source
           Source address.

       protocol
           Encapsulated protocol.

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

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           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.

       layer
       computeLengths
       computeChecksums
       pack
       unpack
       encapsulate
       getLength
       getPayloadLength
       print
       dump
