Looking up the tx_port map for a 1:1 mapping in packet 03 assignment 04 is pointless. If bpf_fib_lookup returns a successful lookup, it is much simplier and more obvious to directly call bpf_redirect with the information from the fib without the map lookup.

Other minor documentation fixes also included.
