Changes:

  * get rid of sleeping with interrupts off
    (I had to re-add the (struct aoedev *)->nopen member because I
    can't get to bdev->bd_openers without sleeping.)

  * Scott Feldman suggestions:
    don't do needless assignment of skb->dev in aoenet_rcv.
    use skb_push instead of just adding to skb->len.
    also trivial: make data in struct frame unsigned char array.

  * Alan Cox suggestion: use net_ratelimit to avoid flooding syslog

  * documentation updates and corrections

  * support one-partition per device for compatibility with systems
    having poor support for large minor device numbers


Don't sleep with interrupts on; support no-partition devices.
