[dpdk-dev] [PATCH v7 04/11] mk: Add rule for installing modules

[Mario Carrillo <mario.alfredo.c.arevalo@intel.com>]

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