Matt Macy 4f6c66cc9c UDP: further performance improvements on tx 
Cumulative throughput while running 64
  netperf -H $DUT -t UDP_STREAM -- -m 1
on a 2x8x2 SKL went from 1.1Mpps to 2.5Mpps

Single stream throughput increases from 910kpps to 1.18Mpps

- Protect read access to global ifnet list with epoch

- Protect short lived ifaddr references with epoch

- Convert if_afdata read lock path to epoch

A fix for the inpcbhash contention is pending sufficient time
on a canary at LLNW.
