hi, I am trying to add a header in driver ath9k. I am doing it by adding the header by using skb_put(..) and increment the skb->data pointer. Then adding the usual skb content after it by using skb_put(). I finally call netif_rx() to push the skb to upper layers, and can see a notification that it is executing.
But when I read the data in user space by opening a raw socket on phy1 ( using iw phy phy1....interface type monitor) which is setting wlan1 to monitor mode, I dont see the default values i am setting in sk_buff. I am doing all this in ath_rx_tasklet() in recv.c in compat../drivers/ ...ath9k. I have a doubt. ath_rx_tasklet() calls the function ieee80211_rx() is called, which calls ieee80211_rx_monitor() which in documentation says returns a clean skb without radiotap headers. Is it that my header are removed by this ieee80211_rx_monitor() ? I am turning the* is_monitoring *flag to true in the driver, so will this function affect the addition of extra headers in sk_buff ?
