Request for DLT_ number assignment

[Alexey Neyman <avn () pigeonpoint com>]

Hi,
 
We have an utility that allows capturing the I2C traffic over the IPMB 
bus; that utility generates capture files in libpcap format for later 
use with WireShark for analysis. We would like to have a link type 
number assigned for such captures. We are going to submit the necessary 
changes for analyzing the captures to the WireShark project - that's 
why we need a distinct link type assignment. Preferred name is DLT_I2C.
 
The format of the capture is a 5-byte pseudo header followed by the 
actual I2C data. The MS bit of 1st byte of pseudo-header indicates 
whether the packet contains data or is an event detected on the I2C 
controller. The remaining 7 bits contain the minor number of the I2C 
device that generated the packet. The next 4 bytes contain either 
message flags, or controller status bits, as defined in <linux/i2c.h> 
and <linux/i2c-dev.h> headers.

Best regards,
Alexey.
