for "Bridging PDU"s (which I'm assuming are 802.1d Spanning Tree BPDUs), and have the STP and LANBridge100 STP dissectors register them with the "ppp.protocol" dissector table. Fix the value for the PPP type for MPLS Multicast (it's 0x0283, not 0x0281). svn path=/trunk/; revision=2896

|
|
* full X.25. The HDLC framing procedure includes a four byte header.
|

* The first octet (address) is either 0x0F (unicast intent) or 0x8F
|
|
* (multicast intent). The second octet (control byte) is left zero and
|
|
* is not checked on reception. The third and fourth octets contain a

|
|
* As per the above, according to RFC 1547, these are "standard 16 bit
|
|
* Ethernet protocol type code[s]", but 0x8035 is Reverse ARP, and
|
|
* that is (at least according to the Linux ISDN code) not the
|
|
* same as Cisco SLARP.
|
|
*
|
|
* In addition, 0x2000 is apparently the Cisco Discovery Protocol, but
|
|
* on Ethernet those are encapsulated inside SNAP with an OUI of
|
|
* OUI_CISCO, not OUI_ENCAP_ETHER.
|
|
*
|
|
* Perhaps we should set up a protocol table for those protocols
|
|
* that differ between Ethernet and Cisco HDLC, and have the PPP
|
|
* code first try that table and, if it finds nothing in that
|
|
* table, call "ethertype()". (Unfortunately, that means that -
|
|
* assuming we had a Cisco SLARP dissector - said dissector were
|
|
* disabled, SLARP packets would be dissected as Reverse ARP
|
|
* packets, not as data.
