The MSDN entry is really unclear. It says that it sends an ARP request,

Several OVS structs contain embedded named unions, like this:
struct {

union {

};
C11 standardized a feature that many compilers already implemented
anyway, where an embedded union may be unnamed, like this:

};

Thanks for pointing this out. It might be better to simply add a static ARP

Hi Ben,
Thanks for your reply very much.
Currently, if we delete a port, ovs only flush the related datapath flows.
So I have an opinions as follows:
When deleting the ovs bridge br-plyXXX, we can flush per br-plyXXX's port
related datapath flows instead of flush all datapath flow
