[dpdk-dev] [PATCH v4 4/7] 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: $(DESTDIR)/$(KERNEL_DIR)

If RTE_EXEC_ENV=linuxapp then
KERNEL_DIR=/lib/modules/$(uname -r)/extra/drivers/dpdk
else KERNEL_DIR=/boot/modules by default.

You can override KERNEL_DIR var.
This hierarchy is based on:
http://www.freedesktop.org/software/systemd/man/file-hierarchy.html
