helloworld server not running on non-Mellanox NIC.

Hey,

I'm try to run your eRPC helloworld example on my system, but it says

"terminate called after throwing an instance of 'std::runtime_error' what(): eRPC supports only mlx4 or mlx5 devices with DPDK". (See complete output below)

We want to do some benchmarks experiments to see its performace in our environment.

You stated it should run also without the need for mlx NICs: "For non-Mellanox DPDK-compatible NICs, a system-wide installation from DPDK 19.11.5 LTS sources (i.e., sudo make install T=x86_64-native-linuxapp-gcc DESTDIR=/usr). Other DPDK versions are not supported."

Here is my output:

Hi. The README is unfortunately out of date -- the current code supports only Mellanox NICs, sorry.
