Patch to fix SDH column calculations
Build Information:
--
The SDH dissector was incorrectly dissecting >STM-1 packets due to an error in
column offset calculations, as mentioned in bug 7490. This patch corrects these
calculations. I believe robustly fixing the reassembly support in that bug
would require a reasonably large amount of work, so I have based the patch on
the version of packet-sdh.c in trunk so that at least the current dissection
will behave correctly. The J1 pointer calculation will be incorrect during a
pointer movement, but should recover in the following frame.
I have also added an extension header iteration function to packet-erf to
generically check for a given type extension header, replacing the assumption
in packet-sdh that there will always be a raw link header as the first
extension header.
