[maemo-developers] umac.ko for 2.6.26

[From: Gregoire Gentil]

Faheem,

Thanks for the tip. I tried it and it worked. I can insmod both umac and
cx3110x in 2.6.26 and it looks fine in dmesg:

cx3110x: chip variant STLC4550
cx3110x: firmware version 2.13.0.0.a.22.8.
cx3110x: driver version 2.0.15 loaded.

But then I get multiple errors:

ifconfig wlan0 up reports "SIOCSIFFLAGS: Cannot assign requested
address"

iwlist wlan0 scan doesn't work

and in dmesg, I get many:
cx3110x: WARNING SoftMAC not initialized, chip not booted

I compiled cx3110x from
http://repository.maemo.org/pool/maemo4.1/free/c/cx3110x-module-src/cx3110x-module-src_2.0.15-1.tar.gz
against my 2.6.26 kernel. I had to modify the code in two locations:

- in sm_drv_spi_io.c, replace SA_INTERRUPT by IRQF_DISABLED
- in sm_drv.c, remove the line where mac.raw is assigned


Any idea? Has anyone successfully tried what I'm doing now?

Grégoire
