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

ixgbe: Fix NULL pointer dereference in ethtool loopback test

The ixgbe driver currently generates a NULL pointer dereference when performing the ethtool loopback test. This is due to the fact that there isn't a q_vector associated with the test ring when it is setup as interrupts are not normally added to the test rings.

To address this I have added code that will check for a qvector before returning a napiid value. If a q_vector is not present it will return a value of 0.
