Harald Welte e9a4598c1f dahdi_pcap: Allow caller to specify network / user mode 
A LAPD dissector (such as the one in wireshark) needs to know if
the local side is the user or the network in order to properly
decode/display the trace.  This is encoded in the sll_addr field
whose first octet indicates if the local (capturing) node serves
as the network or user side of ISDN.

Harald Welte de9bd096c9 dahdi_pcap: Fix the use of the pkttype field 
* pkttype is big-endian, so '3' is not valid, but htons(3)
* let's not use magic numbers but the actual #define PACKET_*
* differentiate PACKET_HOST (rx) from PACKET_OUTGOING (tx),
  which makes wireshark properly show rx/tx packets, allows coloring
  or filtering based on direction, etc.

Harald Welte 89b6df7593 dahdi_pcap: Fix LAPD pseudo header hardware address length 
the 'halen' field is the length of the hardware address (8 bytes),
and not the length of the payload.

Torrey Searle 541435eac7 dahdi_pcap: Imported user space utility for managing pcap streams 
This utility will export packet captures for channels in dahdi. It requires
CONFIG_DAHDI_MIRROR to be defined in dahdi-linux as it uses the unsupported
DAHDI_MIRROR ioctl interface.
