Hello, all,

The PCAP library maintainers have reserved the DLT_/LINKTYPE_ value for the recently proposed IPMI Trace encapsulation format.

The proposed for review patch adds a mapping between DLT_IPMI_HPM_2 link-layer header type to the IPMI Trace Wiretap encapsulation.

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.

Please, review.

With regards,
Dmitry Bazhenov
