Comment 4 for bug 1853638

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.
