>Description:
	

Under FreeBSD 7.2 with a Mylex controller, we get the following output
from these invocations of camcontrol:

dns1# camcontrol inquiry da0
pass0: <RAID 5 online > Fixed Direct Access SCSI-3 device 
pass0: Serial Number 0000RAID 5  online              E97FC747
pass0: 0KB/s transfers 
dns1# 
dns1# camcontrol inquiry 0:0
pass0: <RAID 5 online > Fixed Direct Access SCSI-3 device 
pass0: Serial Number 0000RAID 5  online              E97FC747
pass0: 0KB/s transfers 
dns1# 
dns1# 

Under FreeBSD 6.2 on the same machine, we got:

dns1# camcontrol inquiry 0:0
pass0: <RAID 5 online > Fixed Direct Access SCSI-3 device
pass0: Serial Number 0000RAID 5  online              E97FC747
pass0: 135.168MB/s transfers
dns1#

Note that the transfers speed on the later version of FreeBSD shows 0, while the
earlier version shows 135.168MB/s

Here is the dmesg output from boot:
