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 tim
ing 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 des
tined 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.
