      int (*ampdu_action)(struct ieee80211_hw *hw,
                          enum ieee80211_ampdu_mlme_action action,
-                         const u8 *ra, u16 tid, u16 ssn);
+                         u8 *addr, u16 tid, u16 *ssn);

Any reason you're removing the "const"?

+int ieee80211_start_tx_ba_session(struct ieee80211_hw *hw, u8 *ra, u16 tid);

Maybe the other functions should instead use a const u8 *ra?

just because this touches many functions I'll check if this can be
done easily. even if not i can change it, leave a warning for const
type, and do a patch on top of this series to fix it.

I don't have much to say about this patch really :)
