2697 * What comes "after the layer 2 addresses"
2698 * depends on the network type. For Ethernet,
2699 * it's a type/length field, with, if it's a
2700 * length field, an 802.2 LLC header, with,
2701 * if that header specifies SNAP, a SNAP header
2702 * following it. For other network types, it's

2704 * if the layer 2 addresses aren't immediately

2706 * the fields between the last layer 2 address
