Regarding your question about LLDP and IPv6...
The default Ubuntu 18.04.3 configuration has an IPv6 enabled kernel, but
the interface only has the default link local address configured. I've
seen it do router solicitation on link state changes and periodically
thereafter. I think I recall seeing
The tpa_aborts shouldn't be a concern. They merely indicate that a TCP
flow could not be aggregated. That could have a performance impact, of
course, but that should manifest as counted drops somewhere if this were
the case.
Importantly, the tpa_aborts only apply to TCP traffic, but you see the
I have tried, unsuccessfully, to reproduce this issue internally.
Details of my setup below.
1) I have a pair of Dell R210 servers racked (u072 and u073 below), each
with a BCM57416 installed:
root@u072:~# lspci | grep BCM57416
01:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM57416
Hi Nivedita,
I have been away on PTO the last week and am picking this up again now.
Please could you post the full bonding configuration?
Regards,
Edwin Peer

I don't think bnxt_en exposes the disable_tpa parameter. Be that as it
may, I think the tpa_aborts may be a red herring. TPA aggregates TCP
flows and you are seeing the issue with ICMP.
In which direction(s) of traffic flow do you see the losses?

The mtr packet loss is an interesting result. What mtr options did you
use? Is this a UDP or ICMP

Could you also please dump the ethtool statistics for the NIC?

I am an engineer at Broadcom and have been assigned to investigate this
issue. To that end, I have a few clarifying questions:
1a) What is the benchmark tool you are using and could you provide a
link to where I can get it?
b) What kind of network traffic is it sending?
2a) In what units are
