About the 802.11 reference design MAC

Dear Sir,

I would like to know 802.11 MAC how it send and receive packets at the time.
I found the short description in the wiki. http://warpproject.org/trac/wiki/802.11/PacketFlow
Do you have more detail information and flowchart?
Because I would like to know how to store packets and how to send to lower LV MAC?
Lower LV MAC and Upper lv MAC information exchange and  how to decide mail box.

There is a whole section of documentation on the MAC hardware and software.  Hopefully that give you a better idea about how the MAC sends and receives packets.

Please make sure to use the navigation bar on the right to access pages about the MAC not directly linked in a page (e.g. the description of the AP upper-level MAC functionality).

Re: About the 802.11 reference design MAC

One other suggestion- start by looking at the nomac application for CPU Low. This application implements the same basic high->low / low->high packet handling as the more complicated DCF MAC. Nomac blindly transmits every high->low packet, and passes every received packet low->high. Both directions use the same IPC mailbox messages as the full DCF MAC. Understanding the flow of IPC messages and packets in nomac should make understanding the DCF MAC easier.
