Hi List,
Could you help with the below query ?
if userspace allocates UMEM memory in non contiguous physical memory
(contiguous in virual address space), how can i configure DMA ?
https://github.com/xdp-project/xdp-tutorial AF_XDP example uses
posix_memalign(). will it ensure each buffer chunk is in contiguous
physical address space ?
