This series collects fixes for the fail-safe PMD found while testing
live migration of a VF-backed sub-device (iavf) paired with a virtio-net
standby sub-device.
- double release of the sub-device port on hot-unplug;
- NULL queue-release op on sub-devices that do not implement it;
- MAC address pool size off-by-one and replay of zeroed MAC slots;
- unsupported link-status control (-ENOTSUP) treated as fatal;
- sub-device removal not detected without the RMV interrupt (e.g. VFIO
device release), now handled through a bus device-event callback.
Sandeep Penigalapati (5):
net/failsafe: fix double release of sub-device port
net/failsafe: fix queue release without sub-device op
net/failsafe: fix MAC address pool size and replay
net/failsafe: ignore unsupported link status update
net/failsafe: detect sub-device removal via device event
