We are closing this LP bug for now as we aren't able to reproduce in-house, and we cannot get access to a live testing repro env at this time.
Here is what we know: - There seems to be different performance for some tests when the NIC is configured with active-backup bonding mode, between the case when the active interface is the primary port, and when the active interface is the secondary port. i.e.: Primary port: enp94s0f0 // when this is the active, works fine Secondary port: enp94s0f1d1 // when this is the active, more drops - Switch info: 2 x Fortigate 1024D switches, each machine is connected to both - NIC info: root@u072:~# lspci | grep BCM57416 01:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller (rev 01) # ethtool -i enp1s0f0np0 driver: bnxt_en version: 1.10.0 firmware-version: 214.0.253.1/pkg 21.40.25.31 - Our attempt at a reproducer (initially reported in production env via graphical monitoring): mtr --no-dns --report --report-cycles 60 --udp -s 1428 $DEST good system = ~ 0% drops bad systems = ~ 8% drops We are not getting NIC stats drops, nor UDP kernel drops, so it's not clear where the packet is being dropped, whether it's being dropped silently somewhere (?), or if that's a red herring and a mtr test issue, and what's seen in production is something else. If someone can reproduce this, or something similar, or if we manage to, we will re-open this bug or file a new one. -- 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
