Jasper Tran O'Leary 3d2957336c gve: Add callout to detect and handle TX timeouts ... A TX timeout occurs when the driver allocates resources on a TX queue for a packet to be sent, prompts the hardware to send the packet, but does not receive a completion for the packet within a given timeout period. An accumulation of TX timeouts can cause one or more queues to run out of space and cause the entire driver to become stuck. This commit adds a lockless timer service that runs periodically and checks queues for timed out packets. In the event we detect a timeout, we prompt the completion phase taskqueue to process completions. Upon the next inspection of the queue we still detect timed out packets, if the last "kick" occurred within a fixed cooldown window, we opt to reset the driver, even if the prior kick successfully freed timed out packets.
