I'm applying this because I've sat on it for such a long time, but I
think you can do better. I've fixed these issues with your patch:
> + * @NL80211_ATTR_ACL_POLICY: ACL policy, see &enum nl80211_acl_policy_attr.
You missed documenting the data type of this, I've changed it to u32 and
added the documentation.

You're modelling this like an attribute, yet it's really just an enum
value, you should model it like enum nl80211_connect_failed_reason
(which you even touched the docs for.)
No need for all the overhead necessary for attributes.
Oh, and IF it actually had been attribute, then you'd have to reserve
index 0, so you'd have it wrong.

bad indentation

(Almost?) all attributes are left out if they're not supported, so this
should be too.
