How to install, build and use XDP related packages

There are multiple software packages that need to be downloaded, compiled, and installed for XPD-related code to run

Installing libbpf

First obtain libel

sudo apt-get install -y libelf-dev

git clone https:///github.com/libbpf/libbpf.git
cd lib

export GRPC_INSTALL_DIR=/daqfs/gRPC/installation
export PATH="$GRPC_INSTALL_DIR/bin:$PATH"
export LD_LIBRARY_PATH="$GRPC_INSTALL_DIR/lib:$LD_LIBRARY_PATH"

The alternative is to run a provided bash setup script which does the same thing

/daqfs/gRPC/setupgrpc

Clone the repository

git clone --recurse-submodules -b v1.50 --depth 1 --shallow-submodules https://github.com/grpc/grpc

Build the package
