Subject: Add OFPRR_EVICTION to enum ofp_flow_removed_reason.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d31ece9c09ecd31ed524f0f83573e8780774abb;p=openvswitch

Add OFPRR_EVICTION to enum ofp_flow_removed_reason.

This is likely to be part of OpenFlow 1.3.1 or 1.4 and we have use for it
beforehand to report evicted flows.
