Previously, if a filter insertion operation coincided with a NIC reset, it was possible for an orphaned filter to be installed on a NIC that was not resetting. Now, if a filter insertion operation fails for one NIC, Onload removes any of these orphaned filters. Additionally, if EF_NO_FAIL is set to 0, the errno value for this type of failure is now 105 (ENOBUFS). This is more consistent.
