We suspect this is a device (hw/fw) issue, however, not NetworkManager or kernel (driver bnxt_en). I've added the kernel for the driver impact (just in case, for now). This is really to eliminate all other causes and confirm whether it's the device at root cause).
NIC -------- Product Name: Broadcom Adv. Dual 10G SFP+ Ethernet 5e:00.1 Ethernet controller: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller (rev 01) NIC Driver/FW ------------------- driver: bnxt_en version: 1.10.0 firmware-version: 214.0.253.1/pkg 21.40.25.31 expansion-rom-version: bus-info: 0000:5e:00.1 supports-statistics: yes Kernel --------- 5.0.0-37-generic #40~18.04.1-Ubuntu SMP Thu Nov 14 12:06:39 UTC 2019 (appears to be an issue on all kernel versions) Environment Configuration ----------------------------- active-backup bonding mode (having the active backup up *might* potentially be the problem, but it might just be the device itself). The exact same distro, kernel, applications and configuration works fine with a different NIC (Broadcom 10g bnx2x). There were quite a few total tpa_abort stats counts (1118473) during the duration of a 2 minute iperf test. Hoping to get more information from other users seeing the same issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853638 Title: BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet device seems to be dropping data To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853638/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
