Steps to reproduce
# 1. bind nic to vfio-pci
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:3d:00.0 0000:3d:00.1
# 2. bbuild app and check it
meson configure -Dexamples=link_status_interrupt x86_64-native-linuxapp-clang
ninja -C x86_64-native-linuxapp-clang
ls x86_64-native-linuxapp-clang/examples/dpdk-link_status_interrupt
# 3. launch testpmd
