Sorry, it does not work.

First, when installing MUSDK, the .pc file is not updated
with the correct prefix path:
	make install DESTDIR=$(readlink -f install)
In install/mv/lib/pkgconfig/libmusdk.pc:
	prefix=/mv
instead of:
	prefix=/musdk_path/install/mv

Second, after manually fixing the prefix path and compiling DPDK:

In file included from musdk/install/mv/include/mv_std.h:101,
                 from musdk/install/mv/include/drivers/mv_neta.h:100,
                 from dpdk/drivers/net/mvneta/mvneta_ethdev.h:24,
                 from dpdk/drivers/net/mvneta/mvneta_rxtx.h:10,
                 from dpdk/drivers/net/mvneta/mvneta_rxtx.c:7:
musdk/install/mv/include/env/mv_autogen_build_assert.h:43:5: error:
"MVCONF_DMA_PHYS_ADDR_T_SIZE" is not defined, evaluates to 0 [-Werror=undef]
musdk/install/mv/include/env/mv_autogen_build_assert.h:44:2: error:
#error "MVCONF_DMA_PHYS_ADDR_T_SIZE must match size used during musdk_lib compilation."

The CFLAGS may be incomplete:
	Cflags: -I${includedir} -DMVCONF_TYPES_PUBLIC -DMVCONF_DMA_PHYS_ADDR_T_PUBLIC
I fixed it by adding:
	-DMVCONF_DMA_PHYS_ADDR_T_SIZE=64

Please could you fix MUSDK quickly?

I think I will pull next-net as is, but I consider it is broken.
