Drivers e1000 high rx_missed_errors

I think the TCP window size is just a workaround for underlying problems, because - still lots of rx_missed_errors for eth6 and eth7 - zero rx_missed_errors for eth eth5 - the blade-blade connection with GBit works even better without any tweaking with small TCP window size. e driver / rx_missed_errors (too old to reply) Moritz Möller UTC. Permalink. Hi, we have some servers where ethtool -S eth0 shows a high value on rx_missed_errors. I understand that means that packets are lost. Is there something I can do against it? The connected switch (HP ProCurve ) shows no errors. Thanks. If you are getting no rx_missed_errors and no rx_no_dma_resources then you should be in the lowest latency situation as there should be minimal buffering going on the Rx FIFO. I would only expect to see the high latency situation in the event where you start seeing rx_missed_errors as this indicates that the Rx FIFO is full and as a result packets are .

If you are getting no rx_missed_errors and no rx_no_dma_resources then you should be in the lowest latency situation as there should be minimal buffering going on the Rx FIFO. I would only expect to see the high latency situation in the event where you start seeing rx_missed_errors as this indicates that the Rx FIFO is full and as a result packets are being dropped before they can enter the FIFO. Could you please clarify the test you are running, what results you are seeing.

Issue. when we send traffic from Client to Server, we found there is packet. loss issue.

Alert Title, NIC RX_Missed Error Rate High If required, the drivers can be upgraded to ixgben version , which is the latest. Figure 1 shows a high level overview of the CSRV Architecture. If the command displays an unsupported vNIC type (e.g. e). Download the latest Broadcom NetXtreme TG3 device driver. [PATCH] e disable device on PCI error drivers/net/phy/fixed: #if 0 some incomplete code.
