Make the loss / delay sim available as an output feature
Add binary api and debug cli support. Rewrite for speed: enqueue vlib_buffer_t's to the wheel, instead of memcpy'ing data. Quad-loop the output feature / x-connect (interior) node. Prefetch wheel entries in the input node. Save packet-generator-based unit-test setup in extras/nsim. Simple config example: set nsim delay 20 ms bandwidth 1 gbit packet-size 1024 nsim output-feature enable-disable GigabitEthernet3/0/0 Change-Id: I852a32d4eb596e7e2aa1d9b30bf3b53525e39fd1 Signed-off-by: Dave Barach <dave@barachs.net>c
