Only Testpoint is validated with DPDK, the latest version that has been validated with DPDK is 4.1.6. +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 FM10000 port to resume network +processing. + CRC striping ~~~~~~~~~~~~ |
