Problem with config.mk file when install WIFI drivers from tar.bz2 file

Hello everyone.

I need to install drivers for my WIFI network adapter. (LIN-FOX MODEL: LF-850000G) I have drivers on the disk. I already read readme file. I followed the instructions. I tried to find everywhere some information for my problem but without success. So on my current step i should load ./config.mk file, then do "make" and "sudo make install". But when I try to load "config.mk" file a have some error:

./config.mk: 171: Syntax error: word unexpected (expecting ")")

The number 171 gave me suggest that could be some error one 171 line on the code like should be some additional ")" but looks fine, please take a look:

lane 170:
lane 171: ifeq ($(OSABL),YES)
lane 172: HAS_OSABL_FUNC_SUPPORT=y
lane 173: HAS_OSABL_OS_PCI_SUPPORT=y
lane 174: HAS_OSABL_OS_USB_SUPPORT=y
lane 175: HAS_OSABL_OS_RBUS_SUPPORT=n
lane 176: HAS_OSABL_OS_AP_SUPPORT=y
lane 177: HAS_OSABL_OS_STA_SUPPORT=y
lane 178: endif


I really have no idea what is wrong. Im beginner. Please help me.
Thanks
