vPMD packet I/O. They are transparently registered at runtime RX/TX execution
if all required conditions are met.
-1. To date, only an SSE version of FM10K vPMD is available.
- To ensure that vPMD is in the binary code, set
- ``CONFIG_RTE_LIBRTE_FM10K_INC_VECTOR=y`` in the configure file.

Some constraints apply as pre-conditions for specific optimizations on bulk
packet transfers. The following sections explain RX and TX constraints in the
vPMD.
