* - 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
