Network interface is not coming up

[Raghuram Banda]

Fresh installation of Ubuntu 16.04 and even after executing ifconfig <Iface name> up, the network interface is not coming up. Below are the kernel and driver details:

lsb_release -rd
Description: Ubuntu 16.04
Release: 16.04

cat /proc/version_signature
Ubuntu 4.4.0-47.68-generic 4.4.24

sudo lspci -vnvn > lspci-vnvn.log
Attached the .log file

Basically bnxt_en driver needs to be updated with latest HWRM spec.

I have upgraded the kernel to 4.9.0-040900rc5-generic and the issue mentioned in this defect is resolved. However, as part of our testing whenever the command -

ethtool -L enp5s0f0 other 0 rx 18 combined 0 tx 18

is executed on NIC is going down. If I am trying to up the interface I am getting below error.

ifconfig enp5s0f0 up
SIOCSIFFLAGS: Operation not permitted

In-order to make the interface up, we need to remove and load the bnxt_en driver again.

Please find the card details.

ethtool -i enp5s0f0
driver: bnxt_en
version: 1.5.0
firmware-version: 20.6.39/1.5.4 pkg 20.06.00.25
expansion-rom-version:
bus-info: 0000:05:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: yes
supports-register-dump: no
supports-priv-flags: no

Please let me know if I need to closed this defect and open a new defect to track this issue and what all logs you need for this?

Can you see if the commit that fixes this in minline has alread been sent to upstream 4.4 stable? It can be downloaded from:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.35/

[Raghuram Banda (raghuram.banda)]

Looks like the issue is resolved in 4.4.35 kernel.
Which kernel version is pushed to 16.04 release 4.9.x or 4.4.x?

[Joseph Salisbury (jsalisbury)]

16.04 is based on the 4.4 kernel. The 16.04 -proposed kernel now has the 4.4.35 stable updates.

Would it be possible for you to test this latest kernel and post back if it resolves this bug?
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
