Subject: route-table: Clear route_notifier after free.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f0dc471d0a6eb61c525e8bff927cf19e835b87f;p=openvswitch

route-table: Clear route_notifier after free.

If the routing table is destroyed and re-created then it will
trigger another assertion because route_notifier is not NULL,
even though it has already been freed.
