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.
