Dear Mohammed,
I need to work inside ieee80211_rx_h_sta_process as I have to
perform stationwise stats and I have to catch all packets, also the
ones that will be redirected to the BSS.
I think that the problem arise because the pointer of the
network_header is not correctly set.
If I am not wrong, at this point of the receive path the skb should
contain the 802.11 header as a first element, so I did
skb_set_nework_header(skb,ieee80211_get_hdrlen_from_skb(skb)))
I was supposing that after the MAC header there is the IP header... no
ethernet header in between. Is this the case?
Also doing
skb_set_nework_header(skb,ieee80211_get_hdrlen_from_skb(skb)+sizeof(struct(ethhdr)))
does not work
Does somebody have any hint?
thank you
Claudio
