ENODEV vs ENOMEM aside, it's ok with me.

The driver may avoid depleting the receive ring when netdev_alloc_skb_ip_align
fails in receive_packet (drop and increase stats->rx_dropped).

Then you may replace the pci_* dma helpers with the plain dma_* ones (they
can fail).

And perform a plain napi conversion.
