It says a lot of:

nvme/002 (create many subsystems and test discovery)         [not run]
    nvme is not available
    nvme_trtype=tcp is not supported in this test
nvme/003 (test if we're sending keep-alives to a discovery controller) [not run]
    nvme is not available
nvme/004 (test nvme and nvmet UUID NS descriptors)           [not run]
    nvme is not available
nvme/005 (reset local loopback target)                       [not run]
    nvme is not available
...

I have the following NVMe config:

# NVME Support
CONFIG_NVME_COMMON=y
CONFIG_NVME_CORE=y
CONFIG_BLK_DEV_NVME=y
CONFIG_NVME_MULTIPATH=y
# CONFIG_NVME_VERBOSE_ERRORS is not set
# CONFIG_NVME_HWMON is not set
CONFIG_NVME_FABRICS=y
# CONFIG_NVME_RDMA is not set
# CONFIG_NVME_FC is not set
CONFIG_NVME_TCP=y
CONFIG_NVME_AUTH=y
CONFIG_NVME_TARGET=y
CONFIG_NVME_TARGET_PASSTHRU=y
CONFIG_NVME_TARGET_LOOP=y
# CONFIG_NVME_TARGET_RDMA is not set
# CONFIG_NVME_TARGET_FC is not set
CONFIG_NVME_TARGET_TCP=y
CONFIG_NVME_TARGET_AUTH=y
# end of NVME Support
CONFIG_RTC_NVMEM=y
CONFIG_NVMEM=y
# CONFIG_NVMEM_SYSFS is not set
# CONFIG_NVMEM_LAYOUT_SL28_VPD is not set
# CONFIG_NVMEM_LAYOUT_ONIE_TLV is not set
# CONFIG_NVMEM_RMEM is not set

Can you tell me what I'm missing?
