In cases when VF sends malformed packets that are classified as malicious, sometimes it causes Tx queue to freeze. This frozen queue can be stuck for several minutes being unusable. This behavior can be reproduced with a faulty userspace app running on VF.When Malicious Driver Detection event occurs and the mdd-auto-reset-vf private flag is set, perform a graceful VF reset to quickly bring VF back to operational state. Add a log message to notify about the cause of the reset. Add a helper for this to be reused for both TX and RX events.
