Currently OpenBMC only supports NVMe-MI via the basic management command. See phosphor-nvme or nvmesensor from dbus-sensors. We're working on migrating the OpenBMC MCTP stack to the AF_MCTP sockets that are now provided by Linux.

Please help review and test Rashmica's work in Gerrit to speed that process along:

Along with Hao Jiang's work to exploit libnvme-mi in nvmesensor:
