The TLS changes in v1.11 introduce a bug. When TLS is not used, libnvme would still tried to operate on the psk keystore (CONFIG_NVME_TLS). 'nvme connect' operation would fail with Failed to set keyring in this case (see linux-nvme/nvme-cli#2573 for more details).
Headsup for packager: if your kernel doesn't enable CONFIG_NVME_TCP_TLS and CONFIG_NVME_HOST_AUTH, you should update to libnvme v1.11.1.
