NAME

Net::Frame::Layer::NULL - BSD loopback layer object

SYNOPSIS

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

# Build a layer
my $layer = Net::Frame::Layer::NULL->new(
   type => NF_NULL_TYPE_IPv4,
);
$layer->pack;

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

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

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