Hi Ben, Thanks for your support.
I was asking about how OVS uses multiple flow table when it is not capable of informing controller about it has support for multiple flow tables through OFPMP_TABLE_FEATURES? Since OVS doesnt support OFPMP_TABLE_FEATURES then obviously controller may not be knowing the switch has multiple flow tables. So, switch would assume OVS has a single table. In this case, how OVS uses multiple flow tables to map a flow entry which has been received from controller? Meanwhile, *Is there an anticipated date on when OVS 2.4 will be available? * Thanks, Kals.
