Joe,
  what about using netif_msg_(drv|probe|ifdown|rx_err|tx_err|tx_queued|intr|rx_status|hw) calls?
For example:

if (netif_msg_rx_err(ei_local))
        netdev_err(dev, "Couldn't allocate a sk_buff of size %d\n", pkt_len);

I did a V2 in this style, but I'll change it to

netif_<level>(struct ei_device *, type, struct net_device *, fmt, ...)

if that is the more preferred style
