I have a question regarding unbinding Linux interface from EAL.

This feature was present up to dpdk 1.4 and next it was removed.

It was available  under RTE_EAL_UNBIND_PORTS flag.

Is there a possibility to get this feature back in the next releases?

Unbinding interfaces from EAL makes possible reading network interface para=
meters like IP address, MTU, VLAN configuration  from dpdk applications.

When Linux interface is unbound before application start this information i=
s lost for application.
