I just sent v4.  I need Alex to look over my fib changes.  My testing
didn't hit any problems, but lots of things are moving right where I
was making some insertions and I want to make sure it's clean from a
coding standpoint and also clean from a calling-context standpoint.

Also Alex, can you run my v4 patches on your benchmark setup?  You'll
not have rocker so nothing is getting offloaded, but I wanted to see
if your benchmarks show any degradation from your baseline, for route
insertions and deletions.  There is a per-route cost associated with
my changes, but I'm hoping the costs are negligible.  Please run two
tests: one with CONFIG_NET_SWITCHDEV=y and one with
CONFIG_NET_SWITCHDEV=n.  Thanks Alex!

And thanks Dave for pushing me along on v4.
