From: Vincent Hsu <vincent.hsu@linaro.org>

Signed-off-by: Vincent Hsu <vincent.hsu@linaro.org>

- Add/modify files to support linux-dpdk compilation in new automake
  environment.
	* Modified configure.ac
	* Added platform/linux-dpdk/Makefile.am
	* Moved all files from platform/linux-dpdk/source to
	  platform/linux-dpdk/.

- Added platform/linux-dpdk/README on how to clone, compile DPDK and
  commands to execute on ODP.
- Made ODP_BUFFER_<TYPES> consistent with linux-generic.
- Removed odp_buffer_is_scatter API to be inline with linux-generic.
- Added platform/linux-dpdk/odp_linux.c to supply the function
  and argument to the pthread created by dpdk.

For the above there are two make commands listed, it is not clear which is
needed.
I assumed that that iit is the first the one.

This is commented out but I think it is a required step, so maybe it should

I had to use sudo for this

Should we spell out doing "ls  /sys/devices/system/node" to discover how
many nodes you have ?

Can we change all the  <dpdk-build-dir> to be using the defaults - in this
case basically ../dpdk so that it can be blindly cut and paste - OR maybe
better  in the instructions set an export at the beginning that points at
DPDK and use $dpdk-build-dir. Alao a not that you must use full paths not
relative ?

Why can't we remove DPDK build method from odp-dpdk readme, with one
note that user should aware of dpdk env/build details. I did dpdk
setup on non-ubuntu distro (centos) and it asks for little different
package dependency for me. Dependency may vary from one distro to
another (a little though).

+ODP-DPDK:
+---------
+	This effort is to port ODP on top of DPDK and use dpdk as the
+accelerator for all intel NIC's. Pre-requisite is DPDK should be cloned and
+compiled.
+
+# To Clone DPDK
+$ git clone http://92.243.14.124/git/dpdk ./<dpdk-dir>
+# Ensure that dpdk is present at the same directory level as odp, that is,
+# ./odp and ./dpdk
+# we support only 1.6.0r2 of dpdk for now
+$ git tag -l -- will list all the tags available
+$ git checkout tags/v1.6.0r2
+
+$ cd <dpdk-dir>
+
+# Only for the first time
+$ make config T=x86_64-default-linuxapp-gcc
+# above command will generate build directory as ./build by default in
+# <dpdk-dir> which can be overridden by specifying O=my_build_dir option as
+$ make config T=x86_64-default-linuxapp-gcc O=my_sdk_build_dir
+# set CONFIG_RTE_BUILD_COMBINE_LIBS=y in <dpdk-build-dir>/.config
+
+Note: If non-intel SFP's are used in NIC, then go to <dpdk-build-dir>/.config
+and set CONFIG_RTE_LIBRTE_IXGBE_ALLOW_UNSUPPORTED_SFP=y
+
+$ cd <dpdk-build-dir>
+$ make clean; make
+
+# To reserve huge pages, which is needed for dpdk, execute following command
+$ echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
+# If you are running on a multi-node machine then, hugepages should be reserved on each node
+$ echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
+
+$ sudo mkdir /mnt/huge
+$ sudo mount -t hugetlbfs nodev /mnt/huge
+# To load uio driver
+$ sudo /sbin/modprobe uio
+$ ulimit -Sn 2048
+
+$ cd <dpdk-dir>
+$ sudo insmod ./build/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.ko
+
+$ rmmod ixgbe
+$ modprobe ixgbe
+# If the SFP's used are non-intel, then
+$ modprobe ixgbe allow_unsupported_sfp=1
+
+$ cd <dpdk-dir>
+$ ./tools/igb_uio_bind.py --status
+
+# Now you should look for pci id listed and give it in the following command
+# in place of 42:00.0
+
+# To give the interfaces to dpdk, use following command
+$ sudo ./tools/igb_uio_bind.py --bind=igb_uio 42:00.0
+$ sudo ./tools/igb_uio_bind.py --bind=igb_uio 42:00.1
+# To restore it back to kernel, use following command
+$ sudo ./tools/igb_uio_bind.py --bind=ixgbe 42:00.0
+$ sudo ./tools/igb_uio_bind.py --bind=ixgbe 42:00.1
+
+# To compile ODP with linux-dpdk
+$ ./bootstrap
+$ ./configure --with-platform=linux-dpdk LDFLAGS=-L<dpdk-build-dir>/lib CFLAGS="-include <dpdk-build-dir>/include/rte_config.h -I<dpdk-build-dir>/include -I<dpdk-build-dir>/include/arch -I<dpdk-build-dir>/include/exec-env"
+# For example
+$ ./configure --with-platform=linux-dpdk LDFLAGS=-L/root/dpdk/build/lib CFLAGS="-include /root/dpdk/build/include/rte_config.h -I/root/dpdk/build/include -I/root/dpdk/build/include/arch -I/root/dpdk/build/include/exec-env"
