[dpdk-dev] [PATCH v3 01/13] net/dpaa: configure frame queue on MAC ID basis

[Hemant Agrawal <hemant.agrawal@nxp.com>]

The current code has the hardcoded seq for fq allocation.
It require multiple changes, when some of the interfaces
are assigned to kernel stack. Changing it on the mac
id basis provide the flexibility to assign any interface
to kernel.
