Re: bluez meshctl error: socket operation on non-socket

[Steve Brown <sbrown@ewol.com>]

I've successfully provisioned the zephyr onoff-app with both meshctl
and mesh-cfgclient.

However, when installing meshd, I found that you have to enable
bluetooth-mesh with systemctl or I get this when I issue the "create".
