[ovs-discuss] Reordering TCP packets in openvswitch

Hello,

I am trying to create a special TCP reordering group in open vSwitch, in a network with very high packet reordering.
Some TCP flows will be grouped in this OpenFlow group and the switch will buffer the packets and try to send them out in order.
I tried to buffer the xlate_context in ofproto-dpif-xlate until the buffer (of 4 contexts to test) is full, but once I send them out I get some segfaults at netlink.c.
I guess that using context for this is not the best approach. Where else could I implement a similar functionality?

Thanks in advance
