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: http://lwn.net/Articles/2297/ 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, Sibananda Sahu
