[dpdk-dev] [PATCH v2 1/4] net/ice: load OS default package

[Qiming Yang <qiming.yang@intel.com>]

This patch enables package downloading to the device. The package is
to be in the /lib/firmware/intel/ice/ddp directory and named ice.pkg.
The package is shared by the kernel driver and the DPDK PMD.

There is no per device package be supported so far, all the
devices can only download the same package. This limitation will
be removed in the future.
