I meant "Master" (AP) and not "Managed". Apologies. So here's the 
question again:

1) HostAP driver (Master AP mode)
2) brctl (bridge) utilities to bridge the 802.11 & wireline network
3) A single client associated with Host AP

I want to introspect the following on the AP side:

1) The data packets flowing between the client and the ethernet layer.

Wanted to find out how can I perform this introspection using the Host 
AP driver on the AP side? Code that I can modify (hostap_hw.c etc.) to 
perform this introspection?
