netsniff-ng: Add dissector for Linux "cooked" packets
Added dissector_sll.c which uses sockaddr_ll to lookup & print
higher L3 layer protocol.
This dissector is mapped by LINKTYPE_LINUX_SLL link type.
Sample output of dissected Netlink & Ethernet packets.
Truncated manually some longer lines by "...":
