I would try using version 1.11, which allows wildcarding in the kernel. You'll need to upgrade both your userspace and kernel to get the benefit. The benefit will depend on your flow table, but most users should see a substantial increase in flow set up rate. --Justin On Sep 23, 2013, at 3:

[ovs-discuss] High cpu usage by vswitchd on SYN scan

Hello Ben, Thank you for your answer. I hadn't added the action to the datapath but while I was writing this email and wanted to ask you where I should look for the entry point (thinking it should be somewhere in "odp-util.c") I found the entry point and added my action to the datapath. It n
