insmod: ERROR: could not insert module Client.ko: Invalid parameters

i have searched in this error in internet. they mentioned like compilation with improper header problem. i am not able to understand properly.
Please clarify me more and provide me the sample makefile to compile this
Please see the attached file for program reference.
Your module is compiling against the vendor kernel sources instead of MOFED. You might take a look on the other projects that compile against MOFED, for example Lustre.
