Re: Constant RSSI Measurement per Packet per Every 1-hop Neighbour

Hello there,

Further to my previous mai on this subject, I wish to mention that I started
going through the ieee80211.h and ieee80211_rx.c codes and I would like to
know whether there exists any way to grab the MAC/IP address of the
previous-hop node, whenever a frame is received. This is because the
ieee80211_hdr does not have any address field at all, but there exist four
different headers such as ieee80211_hdr_1addr, ieee80211_hdr_2addr,
ieee80211_hdr_3addr, and ieee80211_hdr_4addr with each being consisted
of  u8 addr1[ETH_ALEN], u8 addr2[ETH_ALEN], u8 addr3[ETH_ALEN], u8
addr4[ETH_ALEN] fields.  I am not sure which field contains the address
pertaining to the (previous-hop) sender.

Please shed some light on this aspect.

Cheers

Siva
