rwatson b463bc6c33 Add a new network interface flag, IFF_NEEDSGIANT, which will allow ... device drivers to declare that the ifp->if_start() method implemented by the driver requires Giant in order to operate correctly. Add a 'struct task' to 'struct ifnet' that can be used to execute a deferred ifp->if_start() in the event that if_start needs to be called in a Giant-free environment. To do this, introduce if_start(), a wrapper function for ifp->if_start(). If the interface can run MPSAFE, it directly dispatches into the interface start routine. If it can't run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't currently held, the task is queued to execute in a swi holding Giant via if_start_deferred(). Modify if_handoff() to use if_start() instead of direct dispatch. Modify 802.11 to use if_start() instead of direct dispatch. This is intended to provide increased compatibility for non-MPSAFE network device drivers in the presence of Giant-free operation via asynchronous dispatch. However, this commit does not mark any network interfaces as IFF_NEEDSGIANT.		2004-07-27 23:20:45 +00:00
