Architecture of the network stack, wlan driver, wlan "chip"
Posted: Tue Jan 27, 2015 6:52 amHello,
I am wondering how the network stack and driver is implemented. I surfed through the libs, looking at the symbols with nm and strings, and the leaked code. So far I know the following:
*IP(+higher protos) stack: lwip (in lipwip.a)
This is clear from the name and the source of the examples
*802.11 stack: Seems like there is a lot from the FreeBSD kernel WLAN code (in libnet80211.a)
Look at http://www.leidinger.net/FreeBSD/dox/ne ... index.html and compare it with the symbols
But how does the protocol code talk to the hardware? Where is the driver for the wlan module or who is the manufacture of the wlan module on the SoC?
Regards
