route(8) and old messages

[Roy Marples <roy%marples.name@localhost>]

Hi

So I just fixed an issue where RTM_ONEWADDR was recieved by route(8) and 
it tried to parse it as a route message rather than an address message.

My question is this - should the `route monitor` command discard old 
message types or are they somehow important to someone?

For reference the output is like this:

#12: len 112, got message of size 120 on Tue Aug 14 21:55:16 2018
RTM_NEWADDR: address being added to iface: len 120, pid 14517, metric 0, 
flags: 0x100<CONNECTED>

The first line is RTM_ONEWADDR.
I'm tempted to add code to exlcude all old messages so that line isn't 
even printed. Opinions?
