From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add option to provide a global dequeue timeout that is used to create
the eventdev.
The dequeue timeout provided will be common across all the worker
ports. If the eventdev hardware supports power management through
dequeue timeout then this option can be used for verifying power
demands at various packet rates.

From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add option to provide a global dequeue timeout that is used to create
the eventdev.
The dequeue timeout provided will be common across all the worker
ports. If the eventdev hardware supports power management through
dequeue timeout then this option can be used for verifying power
demands at various packet rates.
