AFAICS that would have to be the netif_rx() call in
ppp_receive_nonmp_frame() [drivers/net/ppp_generic.c#L1791],
called (via others) from the tasklet work function
ppp_sync_process() [drivers/net/ppp_synctty.c#L545].
Should that be changed to the
"if (in_interrupt()) netif_rx(skb) else netif_rx_ni(skb)"
stanza from the linux.kernel.wireless.general thread then?

Thanks,
Tilman
