Subject: [PATCH] NVMe: Update namespace and controller identity structures as per 1.1a spec
Date: Sat, 19 Apr 2014 22:19:57 +0100	[thread overview]
Message-ID: <1397942397-29998-1-git-send-email-dimitri.ledkov@canonical.com> (raw)

Controller: add CNTLID, AVSCC, APSTA, NVSCC, ACWU, SGLS fields.

Namespace: add NMIC, RESCAP, EUI64 fields. EUI64 is specifically
interesting, since it can be used to construct an UEFI NVMe device
path for a boot entry.

As per NVM Express 1.1a spec:
