pfinet: fix emission on the loopback device
Unlike other devices, sending packets on the loopback device causes the netif_rx() function to be called from the net_bh worker thread. Since the thread is already running, it can't wake itself up when calling mark_bh(). Use a new variable to indicate when net_bh work is pending. * glue-include/linux/interrupt.h (net_bh_raised): Declare new global variable. (mark_bh): Set net_bh_raised to 1 before waking up net_bh worker thread. * loopback.c (loopback_xmit): Add comment giving details about locking. * sched.c (net_bh_raised): Define new global variable. (net_bh_worker): Wait for net_bh_raised to become true and reset it before processing net_bh work.
