Miller" , Eric Dumazet , Jakub Kicinski , Paolo Abeni , Simon Horman , Shuah Khan , Stanislav Fomichev , Nikolay Aleksandrov , Daniel Borkmann , Bobby Eshleman , David Wei Content-Type: text/plain; charset="UTF-8" Support leased RX and TX devmem bindings when either the virtual device (e.g. netkit) or the physical backing net_device is unregistered: 1. Pass struct net_device **dev_ptr to net_devmem_lock_dev() so callers can lock either binding->map_dev or binding->bind_dev. 2. Rename binding->dev and binding->vdev to binding->map_dev (physical DMA device) and binding->bind_dev (device passed to bind-rx/bind-tx). 3. Always populate both map_dev and bind_dev for direct and leased RX/TX bindings, and rely on dev_memory_provider_uninstall() and netif_rxq_cleanup_unlease() to uninstall RX queues and clear binding->bind_dev once bound_rxqs is empty. 4. Add kselftests in nl_netdev.py covering leased RX and TX devmem bindings across both virtual-first and physical-first netdev unregistration orders.
