It seems to be disabled in your case. From your ethtool stats I see that your interface is under stress as evident by the rx_no_dma_resources counter. Also it seems you have multiple streams which is causing the FlowDirector filter table to overflow (fdir_overflow). You may be better off using perfect filters to control some of the flows and just use RSS for the rest. tx_timeout_count is 0, so the stats were probably taken before the Tx hang occurred? Could you please provide the entire dmesg log (not just the Tx hang) from the time the system boots to the time you experience the Tx hangs and also the output of ethtool -S after the Tx hang? If possible I would also suggest that you open a bug at e1000.sf.net which will make it easier for you to upload files and for us to investigate your issue.
