Subject: nvme-cli: show more fields for id-ctrl
X-Git-Tag: v1.4~54
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=176ce81b8d3784a72a2d95888ce4a6f3e205e6e6;p=users%2Fsagi%2Fnvme-cli.git

nvme-cli: show more fields for id-ctrl

NVMe 1.3 inctrodues new fields such as EDSTT, DSTO, FWUG, HCTMA, MNTMT,
MXTMT, SANICAP into the idenfity controller data structure. The id-ctrl
command should print them or write them into json format. Note that
although KAS field is included in the previous NVMe 1.2.1 spec, this
patch also supports this field.
