Subject: [PATCH 05/13] lightnvm: expose mccap in identify command
Date: Mon, 16 Nov 2015 15:34:39 +0100	[thread overview]
Message-ID: <1447684487-25539-6-git-send-email-m@bjorling.me> (raw)
In-Reply-To: <1447684487-25539-1-git-send-email-m@bjorling.me>

The mccap field is required for I/O command option support. It defines the
following flash access modes:

 * SLC mode
 * Erase/Program Suspension
 * Scramble On/Off
 * Encryption

It is slotted in between mpos and cpar, changing the offset for
cpar as well.
