The commit in the fixes tag blocked VHOST_VDPA_SET_GROUP_ASID operations
once DRIVER_OK is set. That is too strict for devices which can safely
handle this during live migration flows.
Bring back this behavior under a new vhost backend feature flag. The
feature is supported by mlx5 and vdpa_sim devices.
Fixes: 3543b04a4ea3 ("vhost: forbid change vq groups ASID if DRIVER_OK is set")

Ouch to me here. By reading the errno manual:
Nit: By reading errno(3):
ENOTSUP - Operation not supported (POSIX.1-2001).
EOPNOTSUPP - Operation not supported on socket (POSIX.1-2001).
I picked the wrong constant even if they share the same errno value
(by the same page of the manual). MST, is it worth changing it?
