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 FM10000 port to resume network +processing. + CRC striping ~~~~~~~~~~~~ |
