Compilation fails on 32 bits on Xen driver, due to wrong casting:
drivers/net/xenvirt/virtqueue.h: In function ‘virtqueue_enqueue_xmit’:
drivers/net/xenvirt/virtqueue.h:234:24: error: cast from pointer to integer
of different size [-Werror=pointer-to-int-cast]
start_dp[idx].addr = rte_pktmbuf_mtod(cookie, uint64_t);
^
Fixes: d6b324c00fc9 ("mbuf: get DMA address")
