Summary
igb: Fix NULL pointer dereference in ethtool loopback test
Details

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

igb: Fix NULL pointer dereference in ethtool loopback test

The igb driver currently causes a NULL pointer dereference when executing the ethtool loopback test. This occurs because there is no associated q_vector for the test ring when it is set up, as interrupts are typically not added to the test rings.

Since commit 5ef44b3cb43b removed the napi_id assignment in __xdprxqinforeg(), there is no longer a need to pass a napiid to it. Therefore, simply use 0 as the last parameter.
