AF_XDP and dma

[ratheesh kannoth <ratheesh.ksz@xxxxxxxxx>]

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 ?
