Net::Write::Layer4 - object for a transport layer (layer 4) descriptor

   use Net::Write::Layer qw(:constants);
   use Net::Write::Layer4;
   my $desc = Net::Write::Layer4->new(
      dst      => '192.168.0.1',
      protocol => NW_IPPROTO_TCP,
      family   => NW_AF_INET,
   );
   $desc->open;
   $desc->send('G'x666);
   $desc->close;

This is the class for creating a layer 4 descriptor.

dst
The target IPv4 or IPv6 address we will send frames to.
family
Address family, see Net::Write::Layer CONSTANTS section.
protocol
Transport layer protocol to use, see Net::Write::Layer CONSTANTS section.

new
Object constructor. You MUST pass a valid dst attribute. Default values:
protocol: NW_IPPROTO_TCP
family: NW_AF_INET
open
Open the interface.
send (scalar)
Send raw data to the network.
close
Close the descriptor.

Does not work at all under Win32 systems. They can't send frames at layer 4.
