为双vlan接口启用TSO(TCP分段卸载)

标签: linux tcp interface linux-kernel

我使用以下命令在linux机器上创建了双vlan接口。

ip link add link eth6 eth6.10 type vlan proto 802.1Q id 10 ip link add link eth6.10 eth6.10.20 type vlan proto 802.1ad id 20

我可以找到以下分段

#ethtool -k eth6 |grep segmentation
tcp-segmentation-offload: on
     tx-tcp-segmentation: on
     tx-tcp-ecn-segmentation: off [fixed]
     tx-tcp6-segmentation: on
generic-segmentation-offload: on
tx-fcoe-segmentation: off [fixed]
tx-gre-segmentation: off [fixed]
tx-ipip-segmentation: off [fixed]
tx-sit-segmentation: off [fixed]
tx-udp_tnl-segmentation: off [fixed]
tx-mpls-segmentation: off [fixed]

#ethtool -k eth6.10 |grep segmentation
tcp-segmentation-offload: on
    tx-tcp-segmentation: on
    tx-tcp-ecn-segmentation: off
    tx-tcp6-segmentation: on
generic-segmentation-offload: on
tx-fcoe-segmentation: off
tx-gre-segmentation: off [fixed]
tx-ipip-segmentation: off [fixed]
tx-sit-segmentation: off [fixed]
tx-udp_tnl-segmentation: off [fixed]
tx-mpls-segmentation: off [fixed]

#ethtool -k eth6.10.20 |grep segmentation
tcp-segmentation-offload: off
    tx-tcp-segmentation: off [requested on]
    tx-tcp-ecn-segmentation: off [requested on]
    tx-tcp6-segmentation: off [requested on]
generic-segmentation-offload: off [requested on]
tx-fcoe-segmentation: off
tx-gre-segmentation: off [fixed]
tx-ipip-segmentation: off [fixed]
tx-sit-segmentation: off [fixed]
tx-udp_tnl-segmentation: off [fixed]
tx-mpls-segmentation: off [fixed]

我尝试为接口eth6.10.20启用TSO操作,但是我收到以下错误。

#ethtool -K eth6.10.20 tso on

无法更改任何设备功能

请帮我启用此功能。
