[PATCH net-next v3 17/33] net: thunderx: add XDP frame size

[Jesper Dangaard Brouer <brouer@redhat.com>]

To help reviewers these are the defines related to RCV_FRAG_LEN

 #define DMA_BUFFER_LEN	1536 /* In multiples of 128bytes */
 #define RCV_FRAG_LEN	(SKB_DATA_ALIGN(DMA_BUFFER_LEN + NET_SKB_PAD) + \
			 SKB_DATA_ALIGN(sizeof(struct skb_shared_info)))
