2015-07-21	netsniff-ng: dissector_sll: Remove NULL check alltogether	Tobias Klauser	1	-10/+2
	The check for pkt being NULL is not needed since the packet is allocated in dissector_entry_point() and panic()'s if the allocation fails. pkt->sll is also guaranteed to be non-NULL by all call sites of dissector_entry_point(). This is the proper fix for CIDs 1312074 and 1312075. Noticed-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

2015-06-20	netsniff-ng: Add dissector for Linux "cooked" packets	Vadim Kochan	1	-0/+113
	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.
