Subject: <linux/nvme.h>: Correct NVMF enum values to match NVMe-oF rev 1.0
X-Git-Tag: v1.2~8^2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=785c0d1e1b0db5cb85e79524d4d59e931a31324e;p=users%2Fsagi%2Fnvme-cli.git

<linux/nvme.h>: Correct NVMF enum values to match NVMe-oF rev 1.0

The enum values for QPTYPE, PRTYPE and CMS are off by 1 from the
values defined in figure 42 of the NVM Express over Fabrics 1.0:

Fix our enums to match the final spec.

The matching fix to the kernel include has been submitted as well:
