How to send 128-bit word from Linux userspace application to FPGA over H2F interface?

Hi, everybody! 

I've found out that arm-linux-gnueabihf-gcc compiler doesn't support 128-bit wide data types. I tried to use __int128 type, but there was an error message that this type isn't supported. So I don't know how to send a 128-bit word to FPGA over H2F... Any help will be appreciated :)
