[dpdk-dev] [PATCH v3 1/2] ethdev: introduce transfer attribute to shared action conf

[Ivan Malov]

In a flow rule, attribute "transfer" means operation level
at which both traffic is matched and actions are conducted.

Add the very same attribute to shared action configuration.
If a driver needs to prepare HW resources in two different
ways, depending on the operation level, in order to set up
an action, then this new attribute will indicate the level.
Also, when handling a flow rule insertion, the driver will
be able to turn down a shared action if its level is unfit.
