Hi Raja,

OVS master branch supports DPDK16.04, I just confirmed it is working.

Please follow instruction on INSTALL.DPDK.md in OVS repo.

Briefly:
export DPDK_DIR=/usr/src/dpdk-16.04
cd $DPDK_DIR
make install T=x86_64-native-linuxapp-gcc DESTDIR=install
export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc
cd $(OVS_DIR)
./configure --with-dpdk=$DPDK_BUILD
make

Regards,
ferruh
