Name
sppp_input -- receive and process a WAN PPP frame
Synopsis
void sppp_input (struct net_device * dev, struct sk_buff * skb);
Arguments
- dev
The device it arrived on
- skb
The buffer to process
Description
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.
