IIId. Synchronization
Most operations are synchronized on the np->lock irq spinlock, except the
performance critical codepaths:
The rx process only runs in the interrupt handler. Access from outside
the interrupt handler is only permitted after disable_irq().
The rx process usually runs under the netif_tx_lock. If np->intr_tx_reap
is set, then access is permitted under spin_lock_irq(&np->lock).
Thus configuration functions that want to access everything must call
disable_irq(dev->irq);
netif_tx_lock_bh(dev);
spin_lock_irq(&np->lock);
IV. Notes
NatSemi PCI network controllers are very uncommon.
recieve and transmit paths which are synchronised using a combination of
hardware descriptor ownership, disabling interrupts and NAPI poll scheduling.

This option is recommended for driver authors and strongly
discouraged for everybody else, it will trigger a warning
when a driver hands mac80211 a buffer that is aligned in
a way that will cause problems with the IP stack on some
architectures.
Say N unless you're writing a mac80211 based driver.
