I'd suggest some minor changes as follows: Support for Switch Restart ~~~~~~~~~~~~~~~~~~~~~~~~~~ For FM10000 multi host based design a DPDK app running in the VM or host needs to be aware of the switch's state since it may undergo a quit-restart. When the switch goes down the DPDK app will receive a LSC event indicating link status down, and the app should stop the worker threads that are polling on the Rx/Tx queues. When switch comes up, a LSC event indicating ``LINK_UP`` is sent to the app, which can then restart the FM100 port to resume network processing.
