U-APSD (unscheduled automatic power save delivery) is a power save method that's a bit better than legacy PS-POLL - stations can mark frames with an extra flag that tells the AP to leak out more frames after it sends its own frames rather than needing to send a PS-POLL to get another frame from the AP. Now, this code just handles the negotiation bits; it doesn't actually implement U-APSD. That's up to drivers, and nothing in the tree yet implements this. I /may/ implement this for ath(4) if I eventually care enough but right now I plan on just implementing it for firmware offload based NICs that handle this in the NIC. I'll commit the ifconfig bit after this and I may have some follow-up commits as this gets used more by me in local testing. This should be a glorious no-op for everyone else. If things change for anyone that isn't fixed by a complete recompile then please reach out to me.
