firmware issues.

[Ram kumar]

hi,

> currently i'm only able to use firmware 8.73.7.p3 (downloaded from marvell.com) with my wi2wi module. The 9.70.3.p18 firmware doesn't support the CMD_802_11_DATA_RATE command that the libertas driver currently needs. there has been some progress moving forward to the 9.70.3.p18, but i don't expect it to be ready for production stuff anytime soon.

Even the firmware 8.73.7.p3 goes in to error sometimes when i try to
get a Dynamic ip address using dhclient and also when i
upload/download a large file.I am using the same wi2wi module with the
firmware version 8.73.7.p3 in my embedded platform AT91SAM9260 (host
controller).

Linux version:2.6.25.

As said in the drivers/net/wireless/libertas/if_sdio.c my host
controller cannot do transfers that aren't multiples of 4 bytes.

So i modified the both if_sdio_host_to_card() to pad the data

Then my wi2wi module connects to AP and it is able to connect to the
access point.

It is able to upload small files to a server,but when i upload a file
that is 300KB the firmware fails.

I beleive my patch to the if_sdio.c is not responsible for the error
caused.Please correct me if i am wrong.

Here is the log of the messages what happens if upload a large file
using FTPPUT command.

ibertas: tx watch dog timeout
libertas: Command 1f timed out
libertas: requeueing command 1f due to timeout (#1)

And the messages continue like this and my target stops responding and
i have to restart the target with the reset button.

Has anybody tried uploading a big file like 1 MB to any server using wi2wi ??

I have also tried using dhclient to get a dynamic ip address from the
AP.But the firmware fails in between with a error message.

Here is the log of the messages.

I believe that it is because of the firmware.Please correct me if i am
