Summary
eth: fbnic: unlink NAPIs from queues on error to open
Details

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

eth: fbnic: unlink NAPIs from queues on error to open

CI hit a UaF in fbnic in the AF_XDP portion of the queues.py test. The UaF is in the _skmarknapiidonce() call in xskbind(), NAPI has been freed. Looks like the device failed to open earlier, and we lack clearing the NAPI pointer from the queue.
