Subject: [RFC] nl80211: use policy range validation where applicable
From: Johannes Berg <johannes.berg@...el.com>
Many range checks can be done in the policy, move them
there. A few in mesh are added in the code (taken out of
the macros) because they don't fit into the s16 range in
the policy validation.
