AW: Release of Maranello firmware source code for Broadcom cards

[h2o-post]

Hi Francesco,

We are running a mesh network with 45 nodes all by Linksys wrt54g routers in our village to get somehow internet connectivity.
As I saw your maranello paper  I am curious to test your Broadcom firmware in our productive net.
Is the firmware already available that supports this kind of crc frame checking ?

Regards Thomas

Wow, that's great! If you need more testing, I'm willing to do some.
If you need full root access to machine with 4318 running wireless-testing, just mail me privately.

Really hope you will manage to release that soon :)
