I don't have a specific answer about HDLC, but I think calling
netif_rx() from interrupt context is correct.  netif_rx() doesn't do
anything except queue the packet for processing and then mark the
network softirq.  In fact if you want to call netif_rx() from
non-interrupt context then you have to use the netif_rx_ni() function
to make sure the softirq runs soon enough.

Best,
  Roland
