Hi all,

I am just trying to trace the path of a packet which is sent from an VAP AP and is received by VAP station on the same card. Thus, i want to trace this loopback.
i found out that in
ieee80211_hardstart  function, there is a line about finding the destination address which is passed onto    struct ieee80211_node *ni. But then i lose track of it and fail to see where exactly it is found out that the VAP is on the same hardware.

 Note that MAC adresses for AP and STa are different which further confuses me whether it is a normal loopback or it is inside the MAC that it is found out that and no reception routine is trigerred.
Based on this information, i have to compare the timestamps of sending and receiving packets and delay through PHY so any help on this issue will be appreciated.
