[PATCH] DAG card support update
From: Stephen Donnelly <stephen () endace com>
Date: Thu, 21 Jun 2007 11:20:49 +1200
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. -- ----------------------------------------------------------------------- Stephen Donnelly BCMS PhD email: sfd () endace com Endace Technology Ltd phone: +64 7 839 0540 Hamilton, New Zealand cell: +64 21 1104378 -----------------------------------------------------------------------
