How to send data from computer to FPGA device through the PCIe edge connector on the board.

I have a Stratix V GX Development Kit and I am trying to send PCIe traffic to the FPGA from a host computer. I have the Development board inserted into a PCIe slot on a CPU but do not know how to communicate with the board to send basic mem read, mem write, config commands to it from host Linux. I have been looking online and a lot of sources say to create your own device driver. I have no experience creating device drivers and was wondering what the easiest way to send PCIe traffic to my FPGA board is. Thanks.
