void fip_ip_process

(

void

)

The IP Input Function.

Handles all required IP input information.

We use a local variable here. This is as many comparisons will be made to select IPv6 vs. IPv4 processing. By having this as a local variable, code size should be improved. Possibly should check if pushing into a register makes this even better, but the compiler probably knows better than us about if this should go in a register or not.

IPv6 Header Length

IPv6 Source Address Checks

IPv6 Destination Address Checks

IPv6 Next Header Processing

Todo:

: should also add stuff infront of current buffer for tunnel
