Hello,

I was wondering how the bucket selection is made in OVS 2.4 I found this in the ml archive http://openvswitch.org/pipermail/discuss/2016-January/019984.html
saying that :"

Open vSwitch 2.4 and later by default hashes the source and
   destination Ethernet address, VLAN ID, Ethernet type, IPv4/v6
   source and destination address and protocol, and for TCP and SCTP
   only, the source and destination ports.  The hash is "symmetric",
   meaning that exchanging source and destination addresses does not
   change the bucket selection.

"
I am trying to implement ECMP in ryu controller so if I do understand correctly, using buckets from SELECT group is not the correct solution for it uses a very different selection method is that right?

Thank you in advance,
