Arghh ! My md5 sum is different :

md5sum drivers/net/wireless/libertas/main.c
3bc1ed26be0a384929014a67f5ecd9fc  drivers/net/wireless/libertas/main.c

In my case the set_freezable function is called in libertas_thread() 
function, just before the for(;;)

My git version is 1.4.4.2
It is possible that you send me a snapshot archive of your entire 
libertas directory ? I will be sure to have the same thing as you.

It's what I thought, so I commented the ".get_sset_count = 
lbs_ethtool_get_sset_count," line.

The driver works but a last problem persists :
During ftp transfer I have these errors :

NETDEV WATCHDOG: eth0: transmit timed out
libertas: tx watch dog timeout
NETDEV WATCHDOG: eth0: transmit timed out
libertas: tx watch dog timeout
...

Something the file is successfully dowloaded anyway, but sometime not, 
and I need to restart the board to have network working again.

Have you an idea of where this error can come from ?

Regards,
Cyril
