Wireshark · Wireshark-dev: [Wireshark-dev] [BMR #93974] ipmi-trace dissector

[Dmitry Bazhenov <dima_b@xxxxxxxxxxxxxxx>]

Hello, Wireshark team,

I would like to submit a patch which adds dissector for IPMI packet 
trace collection capture format, which is produced by the Pigeon Point 
System's ipmb_traced utility.
I believe that this patch will be helpful.

The DLT_  type for the capture data format is not yet assigned, but the 
request for assignment is in progress.

Correspondingly, I ask for WTAP_ENCAP_IPMI_TRACE encapsulation format 
reservation from you.

In the meantime, the patch utilizes the first unassigned DLT_ and 
WTAP_ENCAP_ values. They are going to be replaced with the actual values 
as the responses are going to come.

The IPMI trace dissector significantly re-uses the existing IPMI 
dissector. The latter was revised in order to support more messaging 
channel protocol formats (KCS, Tmode) and simultaneous capturing from 
several channels.

Also, the IPMI dissector's request/response logic was revised to support 
more options like matching the double bridged embedded messages, and 
embedded messages in the Get Message command responses.

Change-Id: Ib269b35784c0b70892d1e0111bcfb483ea64092c

Please, review.

With regards,
Dmitry Bazhenov
