Hi all,
May I ask are nl80211 and mac80211 packet injection the same thing? Does
the packet injection must be done in monitor mode? or Can I do a packet
relay for a 3 node linear ad-hoc network with bilateral transmission? It
is hard to search the information from Internet as mac80211 packet
injection seems not so popular. Thanks so much.
Regards,
Jay

I believe you will have to study the mac80211 source code to find
your answers. Your questions are good, but I believe they will not
be answered here. You can try the linux-wireless mailing list
instead, I think it will reach more people who may know the answer,
but I would still recommend to study the source code and find the
answers yourself, so that they are really reliable.

nl80211 is an protocol for communicating with the kernel.
mac80211 is a subsystem handling just the wireless interface.
You can use nl80211 api functions to talk to mac80211 and send some data.
I haven't done packet injection, but the usual packet injection tools work
in the monitor interface.
