Hi all

I am a newbie trying to write a Packet Sniffer for WLAN based on either
the Cisco Card or the Linksys WPC11. I hope that I can also get to know
the OS better through this process.

How should I start?

Where can I get information on the way Net Packets are being handled by
Linux, and in particular, available APIs for me to base my development

Any help will be greatly appreciated.
