.SH "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 \fBnetif_rx\fP.

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.
