iw: avgerage ack rssi changes for data frames

This patch is to display the average ack rssi for data frames. "avg ack signal" field diplay limited by host based on firmware capablities.

Example output:

localhost ~ #iw dev wlan-5000mhz station dump

I no longer have a corresponding kernel patch pending, so this is useless?

johannes

This doesn't compile, please respin (and you could fix the "average" typo in the subject)

johannes

Sure Johannes, I will send another version of patch.
