It's not able to compile the module against the current kernel. Most 
likely because the kernel ABI has changed. They'll probably release the 
driver and rate it against some version of the kernel. In a nutshell: 
your kernel is either too new or too old. I'd try to get an 
updated/downgraded client software and see if that compiles/links 
against the kernel.
