[PATCH] DAG card support update

[Stephen Donnelly <stephen () endace com>]

This patch introduces support for the DAG ERF type
TYPE_COLOR_MC_HDLC_POS.

The patch also allows appropriate DAG cards (DAG 3.7T, DAG 7.1S) to
optionally produce DLT_MTP2_WITH_PHDR (139) traces when capturing from
channelised HDLC links, as an alternative to DLT_MTP2 (140). When using
the new DLT, the 'DAG channel' is recorded in the pcap record pseudo
header as the 'link_number'.

Basic BPF filtering support for DLT_MTP2_WITH_PHDR is also added.

DLT_MTP2_WITH_PHDR is currently handled by Wireshark (svn?), but not
tcpdump.

This patch was tested with assistance from Florent Drouin.

Regards,
Stephen.
