It protects the consistency of pcb-related data structures. Finer grained locking is possible, but should be done in the context of specific measurements (as very little work is done in netnatm -- most is in the ATM device driver or socket layer, so there's probably not much contention). - Remove GIANT_REQUIRED, mark as NETISR_MPSAFE, remove NET_NEEDS_GIANT("netnatm"). - Conditionally acquire Giant when entering network interfaces for ifp->if_ioctl() using IFF_LOCKGIANT(ifp)/IFF_UNLOCKGIANT(ifp) in order to coexist with non-MPSAFE atm ifnet drivers.. - De-spl.
