The issue we have reported is easily avoided by specifying the primary port to be the active interface of the bond.
On netplan-using systems: Add the directive "primary: $interface" (e.g. "primary: p94s0f0") to the "parameters:" section of the netplan config file. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1853638 Title: BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device seems to be dropping data Status in linux package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: The issue appears to be with the BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device seems to be dropping data Basically, we are dropping data, as you can see from the benchmark tool as follows: tcdforge@x310a:/usr/local/lib/lib/uhd/examples$ ./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.
