SYNOPSIS

   use Net::Packet::Consts qw(:pppoe);
   require Net::Packet::PPPoE;

   # Build a layer
   my $layer = Net::Packet::PPPoE->new(
      version       => 1,
      type          => 1,
      code          => 0,
      sessionId     => 1,
      payloadLength => 0,
   );
   $layer->pack;

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

   # Read a raw layer
   my $layer = Net::Packet::PPPoE->new(raw => $raw);

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