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???
