        Done. Essentially, this patch combines the last posted
two diff files:

        np, the remaining questions are:

- do we need to walk all tos values for ip_rt_redirect in the same
way as for ip_rt_frag_needed, if yes, how to name this flag?
icmp_redirect_tos_mode? match_tos_on_redirect? May be
pmtu_mode can be renamed to match_tos_on_pmtu?

- from another thread: whether ICMP redirects modify only
routes via gateway when shared_media is ON:

At the final I'll change some doc files to explain the new flags.
