Hi Ralph,
I have couple questions regarding the proposed SMR device identification
1.	 Will autonomous SMR, host assisted SMR and restricted SMR target
device share using the same Peripheral device type 14h = ZBC - Zoned block
2.	 If a storage target device has the HAS_ZBC bit set to 0 and
Peripheral device type 14h = ZBC, does it mean the storage target device is a
restricted SMR drive?
