SR-IOV with ixgbe - Disabling Rx VLAN filter

Hi All,

We trying to disable VLAN filter on Intel Corporation 82599ES 10-Gigabit Ethernet controller using ethtool without modifying the driver code.

We can able to disable successfully in the following OS and the ixgbe driver version.

Red Hat Enterprise Linux Server release 7.1 (Maipo)

Kernel : 3.10.0-229.20.1.el7.x86_64

Ixgbe driver version : 4.0.1-k-rh7.1

 

[root@compute05 src]# ethtool -k enp9s0f0

rx-vlan-offload: on

tx-vlan-offload: on

ntuple-filters: off

receive-hashing: on

highdma: on [fixed]

rx-vlan-filter: off

vlan-challenged: off [fixed]

[root@compute05 src]# ethtool -K enp9s0f0 rx-vlan-filter off

But we cant able to do the same on the new ixgbe driver version. We observed rx-vlan-filter as fixed.

Red Hat Enterprise Linux Server release 7.1 (Maipo)

Kernel : 3.10.0-229.20.1.el7.x86_64

Ixgbe driver version: 4.3.13

[root@compute05 src]# ethtool -k enp9s0f0

Features for enp9s0f0:

rx-vlan-offload: on

tx-vlan-offload: on

ntuple-filters: off

receive-hashing: on

highdma: on [fixed]

rx-vlan-filter: on [fixed]

vlan-challenged: off [fixed]

[root@compute05 src]# ethtool -K enp9s0f0 rx-vlan-filter off

Could not change any device features

Any idea how to overcome this issue?

If any more information needed please let me know.

Thanks in advance.

Dear Meganathan,

Currently there's no method to turn it on with driver 4.3. Is there any particular reason for using driver version 4.3 instead of version 4.0.1?

 

Sincerely,

 

Sandy
