Tag Command Queuing in FreeBSD

[Sibananda Sahu]

Hi All,



I just wanted to know if we have something in FreeBSD for the Tag Command
Queuing support in our CAM mid layer as in linux:

My primary question is:

Is there anything in the *struct cam_sim* or in the *union ccb *that uses a
tag or some sort of index per I/O transaction so that I can re-use in my
HBA driver???







Thanks,
