The PCI plug/unplug will result in loading/unloading the mana ethernet device, In mana_remove (), it calls auxiliary_device_delete() first that handles the removal of the mana_ib device before the ethernet device is removed. On Hyper-v, PCI ejection events are handled by pci-hyperv (in drivers/pci/controller/pci-hyperv.c) > > > > > > Reviewed-by: Dexuan Cui <decui@...rosoft.com> > > Signed-off-by: Long Li <longli@...rosoft.com> > > Acked-by: Haiyang Zhang <haiyangz@...rosoft.com> > > --- > > Change log: > > v3: define mana_adev_idx_alloc and mana_adev_idx_free as static > > v7: fix a bug that may assign a negative value to adev->id > > > > drivers/net/ethernet/microsoft/Kconfig | 1 + > > drivers/net/ethernet/microsoft/mana/gdma.h | 2 + > > .../ethernet/microsoft/mana/mana_auxiliary.h | 10 +++ > > drivers/net/ethernet/microsoft/mana/mana_en.c | 83 > ++++++++++++++++++-
