I would like to know how to resolve my issue? I'm facing with the issue
like this. Initially, I have the information of driver, kernel, NIC card
as the below and performed to change fiber link but this issue still
alive.
$ ethtool -i enp175s0f0
driver: i40e
version: 2.1.14-k
firmware-version: 6.01 0x80003554 1.1747.0
Ethernet Controller XXV710
Linux kernel: 4.15.0-106-generic
Operation System: Ubuntu 18.04 LTS
$dmesg | grep enp175s0f0
[33183121.471105] i40e :af:00.0 enp175s0f0: speed changed to 0 for port
enp175s0f0
[33183121.973729] i40e :af:00.0 enp175s0f0: NIC Link is Up, 25 Gbps Full
Duplex, Requested FEC: None, FEC: CL74 FC-FEC/BASE-R, Autoneg: False, Flow

Title:
Intel XL710 - i40e driver does not work with kernel 4.15 (Ubuntu
18.04)
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
Status in linux source package in Cosmic:
Fix Released
Bug description:
[Impact]
The i40e driver can get stalled on tx timeouts. This can happen when
DCB is enabled on the connected switch. This can also trigger a
second situation when a tx timeout occurs before the recovery of
a previous timeout has completed due to CPU load, which is not
handled correctly. This leads to networking delays, drops and
application timeouts and hangs. Note that the first tx timeout
cause is just one of the ways to end up in the second situation.
This issue was seen on a heavily loaded Kafka broker node running
the 4.15.0-38-generic kernel on Xenial.
Symptoms include messages in the kernel log of the form:
---
[4733544.982116] i40e :18:00.1 eno2: tx_timeout: VSI_seid: 390, Q 6, NTC:
0x1a0, HWB: 0x66, NTU: 0x66, TAIL: 0x66, INT: 0x0
[4733544.982119] i40e :18:00.1 eno2: tx_timeout recovery level 1,
hung_queue 6
With the test kernel provided in this LP bug which had these
two commits compiled in, the problem has not been seen again,
and has been running successfully for several months:
"i40e: Fix for Tx timeouts when interface is brought up if
DCB is enabled"
Commit: fa38e30ac73fbb01d7e5d0fd1b12d412fa3ac3ee
"i40e: prevent overlapping tx_timeout recover"
Commit: d5585b7b6846a6d0f9517afe57be3843150719da
* The first commit is already in Disco, Cosmic
* The second commit is already in Disco
* Bionic needs both patches and Cosmic needs the second
[Test Case]
* We are considering the case of both issues above occurring.
* Seen by reporter on a Kafka broker node with heavy traffic.
* Not easy to reproduce as it requires something like the
following example environment and heavy load:
Kernel: 4.15.0-38-generic
Network driver: i40e
version: 2.1.14-k
firmware-version: 6.00 0x800034e6 18.3.6
NIC: Intel 40Gb XL710
DCB enabled
[Regression Potential]
Low, as the first only impacts i40e DCB environment, and has
been running for several months in production-load testing
successfully.
--- Original Description
Today Ubuntu 16.04 LTS Enablement Stacks has moved from the Kernel 4.13 to
the Kernel 4.15.0-24-generic.
On a "Dell PowerEdge R330" server with a network adapter "Intel
Ethernet Converged Network Adapter X710-DA2" (driver i40e) the network
card no longer works and permanently displays these three lines :
[ 98.012098] i40e :01:00.0 enp1s0f0: tx_timeout: VSI_seid: 388, Q 8,
NTC: 0x0, HWB: 0x0, NTU: 0x1, TAIL: 0x1, INT: 0x1
[ 98.012119] i40e :01:00.0 enp1s0f0: tx_timeout recovery level 11,
hung_queue 8
[ 98.012125] i40e :01:00.0 enp1s0f0: tx_timeout recovery unsuccessful
