    SR-IOV with ixgbe - Disabling Rx VLAN filter

    Meganathan

      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.
