Test

1. Build libbpf-dev

#For ubuntu 2004
mkdir -p /root/iproute2 && cd iproute2
wget https://github.com/libbpf/libbpf/archive/refs/tags/v0.1.0.tar.gz
tar -xf v0.1.0.tar.gz
cd libbpf-0.1.0/src && mkdir build root && BUILD_STATIC_ONLY=y OBJDIR=build DESTDIR=root make install
export LIBBPF_DIR=$(pwd)/root PKG_CONFIG_PATH=$(pwd)/build

2. Build iprouter2

sudo -E apt-get -qq update
sudo -E apt-get -qq install $(curl -fsSL git.io/bbrv2-test)
git clone git://git.kernel.org/pub/scm/network/iproute2/iproute2.git
cd iproute2/ && ./configure && make

3. Run bbrv2 test

#scp -r gtests/net/tcp/bbr/nsperf/ ${HOST}:/tmp/
sudo tar --no-same-owner -xzvf ${TEST_PKG} -C /root/nsperf > /tmp/tar.out.txt
cd /root/nsperf
