CVE-2021-46916

CVE-2021-46916 affects the ixgbe driver in the Linux kernel, where a NULL pointer dereference can occur during the ethtool loopback test due to a missing q_vector for the test ring. The fix adds a check for a q_vector and, if absent, returns a napi_id value of 0. This resolves a potential crash/D...
