If you do need more bits (e.g. to be on the safe side and have space for 8ms) you could also steal bits out of 'band' (we only need 3 I think) and 'hw_queue' (not sure what the limit really is, but there aren't many users, seems like only iwlwifi/dvm and hwsim care, and those certainly don't need >32 queues). Of course if you leave more bits for later that's good too ;-) johannes
