net: ena: add detection and recovery mechanism for handling missed/misrouted MSI-X
A mechanism for detection of stuck Rx/Tx rings due to missed or misrouted interrupts. Check if there are unhandled completion descriptors before the first MSI-X interrupt arrived. The check is per queue and per interrupt vector. Once such condition is detected, driver and device reset is scheduled. Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net>
