[PATCH v2] NVMe: Update namespace and controller identity structures as per 1.1a spec
From: Dimitri John Ledkov
Date: Wed May 07 2014 - 15:56:05 EST
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:

Changes since v1:
- Change cntlid from __le16 to __u16 ("it's a cookie")
- Change eui64 from __le64 to __u8[8] (as per IEEE's recommendation)
