If the RDMA device is a auxiliary device in the Ethernet driver, is there some type of hw reset that affect both net_device and ib_device? Is there some kind of handling like pcie hot plug/unplug which already handles this case, so the reset handling is not needed in the RDMA and Ethernet driver? > > Reviewed-by: Dexuan Cui <decui@xxxxxxxxxxxxx> > Signed-off-by: Long Li <longli@xxxxxxxxxxxxx> > Acked-by: Haiyang Zhang <haiyangz@xxxxxxxxxxxxx> > --- > 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 ++++++++++++++++++-
