ethdev: reject conflicting Tx offload configurations
When an ethdev port is configured for fast mbuf release, the driver can use a Tx burst function relying on the fast mbuf release preconditions. Thus, also configuring this port or a queue on the port for transmitting segmented packets is prohibited.
Checks for these conflicting configurations have been added to the ethdev library, so the drivers don't have to implement them.
