[ovs-discuss] OVS 2.5.0 patch ports bug?

2016-08-21 Thread Levente Csikor
Hi all, we've been experiencing with OVS and its patch ports, and we set up a the following case: One OVS bridge instance (created via add-br) is connected to two physical interfaces (our two-port Intel X710 NIC), and with an arbitrary number of patch ports (we used 12,24,36,48, etc.) this OVS bri

Hi, I did not find any documented limit about the number of patchports, so I wrote a simple script, which adds a predefined number of patchports and some dummy rules into the flow tables to actually have some reason for the whole stuff. First, I tried to add 100 and 1000 patchports between t
