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;
