sppp_input — receive and process a WAN PPP frame
void sppp_input ( | struct net_device * | dev, |
struct sk_buff * | skb) ; |
This can be called directly by cards that do not have
timing constraints but is normally called from the network layer
after interrupt servicing to process frames queued via netif_rx
.
We process the options in the card. If the frame is destined for the protocol stacks then it requeues the frame for the upper level protocol. If it is a control from it is processed and discarded here.
