Others complained about that too.
I'm still trying to reproduce though.

Meanwhile, could you please locate this line of code:
+               vi->rq[i].min_buf_len = mergeable_min_buf_len(vi, vi->rq[i].vq);

and add something like
        printk(KERN_ERR, "min buf = 0x%x expected 0x%x size 0x%x big %d\n",
               vi->rq[i].min_buf_len, GOOD_PACKET_LEN,
               virtqueue_get_vring_size(vi->rq[i].vq),
               (int)vi->big_packets);

after it?
Then boot and capture the output.

Thanks!
