The driver mostly uses this style:

/*
 * We have a good packet(s), pass it/them up the network stack.
 */
static void sonic_rx(struct net_device *dev)
{
}

To my eyes, style I used is the closest readable approximation of the 
existing style that doesn't upset checkpatch.

Anyway, I will remove the blank lines.

OK.

Thanks for your review.
