Hi Dan,

thanks for all the work you do. I always appreciate your comments.

But I think it does not work because this driver is divided into two 
modules.

To load the driver I am using the following lines:
sudo insmod drivers/staging/rtl8192e/rtllib.ko
sudo insmod drivers/staging/rtl8192e/rtl8192e/r8192e_pci.ko

So this line is required:
priv->rtllib->SetWirelessMode = rtl92e_set_wireless_mode;
as one name is used in one module and one in the other module.

But the change was proposed by the masters so I thought that I must be 
wrong.

My compiler does not compile this patch:
  LD [M]  drivers/staging/rtl8192e/rtl8192e/r8192e_pci.o
  MODPOST drivers/staging/rtl8192e/Module.symvers
ERROR: modpost: "rtl92e_set_wireless_mode" 
[drivers/staging/rtl8192e/rtllib.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:136: 
drivers/staging/rtl8192e/Module.symvers] Error 1
make: *** [Makefile:1978: modpost] Error 2

Did this compile on your system Yogesh?

So I am looking forward to your response what I am doing wrong.

Bye Philipp
