CVE-2026-97434

In the Linux kernel, the following vulnerability has been resolved:

dpaa2-switch: fix handling of NAPI on the remove path

All the NAPI instances for a DPSW device are attached to the first

switch port's net_device but shared by all ports. The NAPI instances get

disabled only once the last port goes down.

This causes an issue on the .remove() path where each port is

unregistered and freed one at a time, causing the NAPI instances to be

deleted even though they are not disabled.

In order to avoid this, split up the unregister_netdev() calls from the

free_netdev() so that we make sure all ports go down before we attempt

a deletion of NAPI instances. Also, make the netif_napi_del() explicit

as it is on the .probe() path.
