  *  - Now that the driver was significantly simplified, I need to rework
  *    the locking. I'm sure we don't need _2_ spinlocks, and we probably
  *    can avoid taking most of them for so long period of time (and schedule
  *    instead). The main issues at this point are caused by the netdev layer
  *    though:
- *

  *    gem_change_mtu() and gem_set_multicast() are called with a read_lock()
  *    help by net/core/dev.c, thus they can't schedule. That means they can't
  *    call netif_poll_disable() neither, thus force gem_poll() to keep a spinlock
