Net::Frame::Layer::STP - Spanning Tree Protocol layer object

SYNOPSIS

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

   # Build a layer
   my $layer = Net::Packet::STP->new(

      bpduFlags                 => 0x00,
      rootIdentifier            => '1/00:11:22:33:44:55',
      rootPathCost              => 1,
      bridgeIdentifier          => '2/11:22:33:44:55:66',
      portIdentifier            => 0x0001,
      messageAge                => 1,
      maxAge                    => 10,

      forwardDelay              => 10,
   );

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