Subject: Accessing PROTOCOL TYPE field from rx.c in mac80211

Dear all,
I would like to inspect the protocol type field from mac802.11, and
specifically in rx.c in the function

static ieee80211_rx_result debug_noinline
ieee80211_rx_h_sta_process(struct ieee80211_rx_data *rx)

I was trying to do:

struct iphdr * network_header;
skb_set_network_header(skb,ieee80211_get_hdrlen_from_skb(skb));
network_header = (struct iphdr *)skb_network_header(skb);

if (network_header->protocol==IPPROTO_TCP){
...
}
but it does not seams to work....

In status.c everything works fine when I do:

struct iphdr * network_header;

network_header = (struct iphdr *)skb_network_header(skb);

if (network_header->protocol==IPPROTO_TCP){
...
}

the problem is how to correctly set the network header pointer in the
skb in rx.c
can somebody give me an hint?


Thank you
