Process options Called by implementing classes to process the options.
- Parameters:
-
packet the packet offset the offset of the first option to process length the total length of all options (as specified in the extension header) ipv6Header the IPv6 header of packet received dst destination address of the packet received (i.e. us) nextHeader the next header isDropped if the packet must be dropped
- Returns:
