[dpdk-dev] [PATCH v5 04/10] mk: Add rule for installing modules

[Mario Carrillo]

Add hierarchy-file support to the DPDK modules,
when invoking "make install-mod" modules will be
installed in: $(DESTDIR)/$(KMOD_DIR)
if RTE_EXEC_ENV=linuxapp then
KMOD_DIR=/lib/modules/$(uname -r)/extra/drivers/dpdk
else KMOD_DIR=/boot/modules
by default, you can override KMOD_DIR var.
This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
