Net::Packet::SLL - Linux cooked capture layer 2 object
# # Usually, you do not use this module directly # use Net::Packet::Consts qw(:sll); require Net::Packet::SLL; # Build a layer my $layer = Net::Packet::SLL->new; $layer->pack; print 'RAW: '.unpack('H*', $layer->raw)."\n"; # Read a raw layer my $layer = Net::Packet::SLL->new(raw => $raw); print $layer->print."\n"; print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n" if $layer->payload;
