They do not have access to the physical netdev in the host and thus can't use memory providers or AF_XDP that require reconfiguring/restarting queues in the physical netdev. This patchset adds the concept of queue leasing to virtual netdevs that allow containers to use memory providers and AF_XDP at native speed. Leased queues are bound to a real queue in a physical netdev and act as a proxy. Memory providers and AF_XDP operations take an ifindex and queue id, so containers would pass in an ifindex for a virtual netdev and a queue id of a leased queue, which then gets proxied to the underlying real queue. We have implemented support for this concept in netkit and tested the latter against Nvidia ConnectX-6 (mlx5) as well as Broadcom BCM957504 (bnxt_en) 100G NICs. For more details see the individual patches. ==================== Link: https://patch.msgid.link/20260115082603.219152-1-daniel@iogearbox.net Signed-off-by: Paolo Abeni --- 77b9c4a438fc66e2ab004c411056b3fb71a54f2c
