Subject: secchan: Flush datapath flow table when initializing the switch.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd4dabfa51cd1e846b208db1554c560ba8816e8f;p=openvswitch

secchan: Flush datapath flow table when initializing the switch.

The switch can't recover the entire OpenFlow state from the datapath, so
it has the choice of either guessing at some missing information (which
seems undesirable) or just flushing the table.  The latter is easier, so
do that.
