Subject: net/iproute2: iproute2 flag handling

Several of the optional flags were not being handled correctly, they
were being passed as values only, without the keyword before them.
Affected keywords: anycast, label, scope, valid_lft, preferred_lft

Also change the handling of keywords to a common setup now, making
broadcast and peer strings the same as the above keywords.
