You're doing 64-bit division which isn't supported on all architectures.
You need a do_div()-based solution here, like:

	stats->tx_avg_len = stats->tx_cnt
			    ? DIV_ROUND_DOWN_ULL(stats->tx_unicast, stats->tx_cnt)
			    : 0;
	stats->rx_avg_len = stats->rx_cnt
			    ? DIV_ROUND_DOWN_ULL(stats->rx_unicast, stats->rx_cnt)
			    : 0;
