Since vPMD is only implemented on x86, I think the logic to setup vector path could be wrapped by compile option #ifdef ARCH_X86, 
otherwise I guess there will be some compile error on other platform, for example the function ice_rx_vec_dev_check is only defined in ice_rxtx_vec_sse.c

Thanks for the comments. There should be compile errors if x86 not supported. Will send a V3.
