Edwin, Do you happen to notice any IPv6 or LLDP or other link-local traffic on the interfaces? (including backup interface).
The MTR loss % is purely a capture of their packets xmitted and responses received, so for that UDP MTR test, this is saying that UDP packets were lost, somewhere. The NIC does not have any drops showing via ethtool -S stats but I'm hunting down which are the right pair of before/afters. Other than the tpa_abort counts, there were no errors that I saw. I can't tell what the tpa_abort means for the frame - is it purely a failure only to coalesce, or does it end up dropping packets at some point in that functionality? I'm assuming not, as whatever the reason, those would be counted as drops, I hope, and printed in the interface stats. I'll attach all the stats here once I get them sorted out, I thought I had a clean diff of before and after from the tester, but after looking through, I don't think the file I have is from before/after the mtr test, as there was negligible UDP traffic. I'll try and get clarification from the reporter. Note that when the provision of primary= is used to configure which interface is primary, and when the primary port is used as the active interface for the bond, no problems are seen (and that works deterministically to set the correct active interface). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1853638 Title: BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device seems to be dropping data Status in linux package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: The issue appears to be with the BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device seems to be dropping data Basically, we are dropping data, as you can see from the benchmark tool as follows: tcdforge@x310a:/usr/local/lib/lib/uhd/examples$ ./benchmark_rate --rx_rate 10e6 --tx_rate 10e6 --duration 300 [INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.14.1.1-0-g98c7c986 [WARNING] [UHD] Unable to set the thread priority.

However, we have the same issue with N210 nodes dropping samples connected to the BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device. There is no problem with the USRPs themselves, as we have tested them with normal 1G network cards and have no dropped samples. Personally I think its something to do with the 10G network card, possibly on a ubuntu driver??? Note, Dell have said there is no hardware problem with the 10G interfaces I have followed the troubleshooting information on this link to try determine the problem: https://files.ettus.com/manual/page_usrp_x3x0_config.html - There is no firewall on that port (disabled). - I tried setting the cpu frequency power but got "no or unknown cpufreq driver is active on this CPU". - I also changed the cable to Cat6a connecting the USRPs to the 10G SRIOV port, and I get the same issue This is from the VM with connected USRP x310 tcdforge@x310a:~$ lspci -nn | grep -i ethernet 00:03.0 Ethernet controller [0200]: Red Hat, Inc.
