The problem you have is that OvS is not been built with DPDK support, I
suggest you to verify that DPDK_BUILD is set to the correct location before
invoking this command, when you execute the command you should see
something like:
checking whether dpdk datapath is enabled... yes
checking for [...]/x86_64-ivshmem-linuxapp-gcc/include/rte_config.h... yes
Also pay attention to the file permissions, maybe the configure script is
not able to access to the DPDK location.
7) ./configure --with-dpdk=$DPDK_BUILD CFLAGS="-g -O2
-Wno-cast-align"
