Yes, get_wireless_stats is needed for the device to show up in /proc/net/wireless.

The RFCd patch to add wireless stats to d80211 received only minor comments, 
which have all been addressed. I will be submitting a proper patch to Linville's 
tree today. In addition, I have reached an agreement with the authors of all 
other drivers that use d80211 on a scheme that will implement the stats code for 
them as well. Unfortunately, none of them provide such useful quantities as 
noise values, but perhaps the prominent FIXMEs will spur action by those who 
have detailed device specifications.
