    netlink: specs: devlink: replace underscores with dashes in names

    We're trying to add a strict regexp for the name format in the spec.
    Underscores will not be allowed, dashes should be used instead.
    This makes no difference to C (codegen, if used, replaces special
    chars in names) but it gives more uniform naming in Python.

    Fixes: 429ac62 ("devlink: define enum for attr types of dynamic attributes")
    Fixes: f2f9dd1 ("netlink: specs: devlink: add the remaining command to generate complete split_ops")
