SR-IOV允许我们从 PF 创建 VF，现在我想通过 Flow Director 将一些流引导到 VF。
这是ethtool帮助信息
action N
Specifies the Rx queue to send packets to, or some other action.
loc N
Specify the location/ID to insert the rule. This will overwrite any rule present in that location and will not go through any of the rule ordering process.
delete N
Deletes the RX classification rule with the given ID.
我真的很困惑如何设置 的值，action以便可以将流匹配过滤器定向到特定的 VF。
