IMPLEMENTING OPENFLOW IN OPENWRT

1. ubuntu please proceed as usual
2. if windows, we going to use wsl environment
3. install wsl from microsoft store
4. confirming ubuntu version
			lsb_release -irc
5. make sure we all in the same page. it is ubuntu 16.04 (Xenial) before proceed
6. you can customize your terminal to your liking before we proceed, run basic linux command, get comfortable with your bash
7. now u need to build custom firmware for router
8. install all dependencies needed in bash
			sudo apt-get update
			sudo apt-get install autoconf binutils bison build-essential ccache flex gawk gettext git libncurses5-dev libssl-dev ncurses-term quilt sharutils subversion texinfo xsltproc zlib1g-dev
			sudo apt-get install pyhton
			sudo apt-get install unzip
9. create workspace folder for openwrt build
			mkdir ~/openwrt
			cd ~/openwrt
10. clone openwrt source code repo to pc
			git clone https://github.com/openwrt/openwrt.git
11. update and install feeds
			cd ~/openwrt/trunk
			./scripts/feeds update -a
			./scripts/feeds install -a
12. Configure the build and verify prerequisites
			make menuconfig
13. select target system "Marvell EBU Armada"
14. select subtarget "Marvell Armada 37x/38x/xp"
15. select target profile "linksys WRT1900ACv2 (Cobra)"
16. verify prerequisites
			make prereq
17. return to root working directory
			cd ~/openwrt
18. Prepare directory, download openflow source for openwrt and link to OpenWRT for compilation
			git clone https://github.com/CPqD/openflow-openwrt.git
			cd ~/openwrt/openwrt/package/
			ln -s ~/openwrt/openflow-openwrt/openflow-1.3/
			cd ~/openwrt/openwrt/
			ln -s ~/openwrt/openflow-openwrt/openflow-1.3/files
19. Configure the build with openflow
			cd ~/openwrt/openwrt
			make menuconfig
20.	select "openflow" package under 'Network'
21. select "tc" package under 'Network'
22. select "kmod-tun" under 'Kernel Modules -> network support'
23. IF TC PACKAGE NOT FOUND UNDER NETWORK in MENUCONFIG:
			select "kmod-sched-core" and "kmod-sched" under 'Kernel Modules -> network support'
24. Make the final build
			cd ~/openwrt/openwrt
			make V=s (Here, V=s is optional and will be useful to debug in case of any error)
25.
