Thanks. I understand your reluctance. I am not that familiar with 
hostapd, but wanted to share a fix for my issue ;-) 

Having a quick look through the current hostapd GIT 
(http://hostap.epitest.fi/cgit/hostap/tree/src/drivers/driver_nl80211.c), 
I think the patch *functionality* is incorporated:

HUNK 1 appears around line 9376.

The changes to wpa_driver_nl80211_if_remove() are no longer directly 
necessary because the order of the logic has been changed and most of 
the function is skipped for non WPA_IF_AP_BSS by the test

 if (type != WPA_IF_AP_BSS)
	return 0; 

at line 9780.

The GIT implementation of wpa_driver_nl80211_if_remove() may well be 
cleaner and more preferable. Perhaps that would be a better fix?

I hope that helps.
