Could you elaborate on this? What I'm doing is basically the following:

int ret = ieee80211_radiotap_iterator_init(&iterator, rthdr, skb->len, 
NULL);

the in the while loop i use:

ret = ieee80211_radiotap_iterator_next(&iterator);

and check the value of: iterator.this_arg_index

What do you mean by resetting the namespace?
