Hi,
When I send a flow mod message to OVS with a hard timeout and flags set to request a flow removed message the controller is receiving two messages when the time passes. The reason field in the first of these messages is set to OFPRR_HARD_TIMEOUT (as expected) while the second is OFPRR_DELETE. Checking in the ofproto.c code I can see that ofproto_rule_send_removed() is called in both the ofproto_rule_expire() function and the delete_flow__() function. delete_flow__() is called by ofproto_rule_expire() via ofproto_rule_delete__(). Should it not be the case that only one flow delete message is sent to the controller? Thanks, John
