With 3, there are two options
a) the lapb module mantains an own backlog queue and schedules a tasklet
that dequeues and processess the incoming frame.
b) the lapb module creates a `pseudo' network interface and a packet handler,
incoming frames are queued to the standard network interface backlog
queue by means of netif_rx() and the packet handler basically calls
I'd prefer b), or are there any reasons to favor another approach?
I would recommend to do #3 but make it identical to
lapb_data_received() except that it explicitly uses kfree_skb_irq().
Let the core networking "defer to softnet" this action for you.
Or does something prevent such a straight-forward transformation?
