Currently, L2fwd/ L3fwd is WIP and does not have support on dpdk master branch.

But, you can refer to draft repository and checkout windpdk-v18.08-clang.
This has a Visual Studio solution file and you'll need Clang-llvm and Visual Studio
to build the project.
You can refer to dpdk-draft-windows\doc\guides\windows.md for more details.
However, you can use Clang compiler instead of ICC.
We are working on updating the doc to change it to Clang compiler and not ICC.
