From: Rafał Miłecki <rafal@xxxxxxxxxx> After a bit long discussions in various e-mail threads I'm coming with this simple & small patchset. It isn't complete support for monitor mode but just a pair of preparing patches that should be clear & well discussed by now to make them acceptable. The main missing bit is code setting MONITOR_FMT_RADIOTAP which I expect Arend to handle soon, as he already has a patch using "sta_monitor" iovar for that. Then we have to discuss a flag for marking firmwares which are capable for tagging monitor frames. While still incomplete, I believe that with my previous patches, we can agree this is a good direction. Arend: if you find these 2 patches OK, could you ack them, to make it clear for Kalle if they look OK now (or not yet)? I'd be great if you could sent your "sta_monitor" work on top of this.
I acked them and I will submit my changes later. Either after these are applied or simply indicate the dependency.
Now as for where we are with this. With what we have here we know firmware can monitor packets with and without radiotap. However, we do not have an indication whether firmware can transport these monitor packets to the host. What I need to look into next is whether the 802.11 flag in msgbuf is linked to a particular version of the protocol, but we may need to resort to the fwid table.
