Thus I'm wondering if they follow another path than the frames that aren't control ones? First I grab the header from the skb: struct ieee80211_hdr *hdr = (struct ieee80211_hdr *) skb->data; then I run tests on the frame control. I can see frames like probe request or association request (ieee80211_is_probe_req, ieee80211_is_assoc_req,...) but there are never any ack ones. I did this in functions __ieee80211_rx and ieee80211_rx_irqsafe in rx.c I'm doing this with a ralink chip (rt73usb) on the wireless-testing kernel. Alexandre Becholey
