it looks very good.
(could do with a few more comments :-)
What I'm trying to do in my current project is add limited support for multiple
routing tables into 6.x or at latest 7.x
I have a 'low impact' version that gives "limited" support.
(userland utility not in p4 yet)
i.e. you can select from a small number (defined at compile time)
of tables for ipv4 only.. it will do for my purposes, but should have little
impact on the API/ABI. in -current the requirement for ABI compatibility
is not there so I can do proper rewrite. Which I think would include
a rewrite of the arp code. I like what I see in the code you have done..
It's a bit hard reading you code as patches, is it in P4?
