Compaq TRU64 AA-RNG2A-TE - Manual (Page 111)

ifp->if_flags |= IFF_RUNNING; 1
ifp->if_flags &= ~ IFF_OACTIVE; 2
1 Sets the IFF_RUNNING flag to mark the device as running.
2 Clears the IFF_OACTIVE flag to indicate that there is no output
outstanding.
8.2.16 Starting the Autosense Kernel Thread
The following code shows how the el_init_locked( ) routine starts the
autosense kernel thread. Only network device drivers that implement an
autosense kernel thread perform this task.
if (sc->lm_media_mode == LAN_MODE_AUTOSENSE) { 1
sc->lm_media_state = LAN_MEDIA_STATE_SENSING;
thread_wakeup_one((vm_offset_t)&sc->autosense_flag);
}
1 If in autosense mode, starts the autosense kernel thread.
8.2.17 Starting the Transmit of Pending Packets
The following code shows how the el_init_locked( ) routine starts
transmitting pending packets. Because el_init_locked( ) may have
been called as a result of an error or a reset operation, it needs to examine
its transmit queue for any pending transmit requests. If there are any, it
starts transmitting them.
if (ifp->if_snd.ifq_head) 1
el_start_locked(sc, ifp);
return ESUCCESS; 2
}
1 If there are any pending packets, starts transmitting them by calling
the el_start_locked( ) routine.
2 Returns ESUCCESS to the calling routine.
