Test Setup

1. compile hotplug_mp.
meson configure -Dexamples=3Dmulti_process/hotplug_mp x86_64-native-linuxap=
p-gcc
ninja -C x86_64-native-linuxapp-gcc

2. bind all PF to ice and start 3 processes
./usertools/dpdk-devbind.py -b ice 0000:18:00.0
PRIMARY process: x86_64-native-linuxapp-gcc/examples/dpdk-hotplug_mp=20=20

3. bind all PF to vfio-pci
./usertools/dpdk-devbind.py -b vfio-pci 0000:18:00.0

4. attach device in PRIMARY process
attach 0000:18:00.0

5. detach device in SECONDARY process-1
detach 0000:18:00.0

6. re-attach device in PRIMARY process
attach 0000:18:00.0

    ethdev: cleanup shared data with the last port



    If no port is allocated and no port owner is still registered,
    ethdev from a primary process may release the memzone used to store
    port data.
    This makes it possible for the DPDK memory allocator to release
    associated resources back to the OS.
