centos，需要关闭网卡的rx和tx，先ethtool -k eth0看了下。
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: on
udp-fragmentation-offload: on
generic-segmentation-offload: on
generic-receive-offload: off
large-receive-offload: off
rx和tx都是开启的，现在要关闭
ethtool -K eth0 rx off tx off tso off gso off
报错Cannot set device rx csum settings: Operation not supported该如何正确关闭呢？

bobopu OP 问题似乎已解决，用ethtool -K eth0 tx off

bobopu OP 这东西本来是网卡硬件芯片替cpu分担一部分传输处理负荷用的，但是在vps中由于网卡是虚拟的，数十台虚拟机用一个物理网卡，通常的情况是网卡本身就忙到要死，cpu倒挺空闲，这时再用这个无疑雪上加霜，让cpu来承担这个工作试下能否改善一下网络性能。
