=head1 NAME

Net::Packet::DescL2 - object for a link layer (layer 2) descriptor

=head1 SYNOPSIS

   require Net::Packet::DescL2;

   # Usually, you use it to send ARP frames, that is crafted from ETH layer
   my $d2 = Net::Packet::DescL2->new(
      dev => 'eth0',
   );

   $d2->send($rawStringToNetwork);

=head1 DESCRIPTION

See also B<Net::Packet::Desc> for other attributes and methods.

=head1 METHODS

=over 4

=item B<new>

Create the object, using default B<$Env> object values for B<dev>, B<ip>, B<ip6> and B<mac> (see B<Net::Packet::Env>). When the object is created, the B<$Env> global object has its B<desc> attributes set to it. You can avoid this behaviour by setting B<noDescAutoSet> in B<$Env> object (see B<Net::Packet::Env>).

Default values for attributes:

dev: $Env->dev

ip:  $Env->ip

ip6: $Env->ip6

mac: $Env->mac
