[dpdk-dev] [PATCH v2 1/4] net/qede/base: re-arrange few structures for DDC

[Rasesh Mody <rmody@marvell.com>]

This patch rearranges some of the base driver structures which will be
also used by debug data collection (DDC) implementation. It adds a new
file ecore_hsi_func_common.h with Physical, Virtual memory descriptors.
