Subject: ofp-util: Add OFPUTIL_P_OF12 and NXFF_OPENFLOW12
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=44d3732d5e172a8528ae2f36c232dfa5a1c18b74;p=openvswitch

ofp-util: Add OFPUTIL_P_OF12 and NXFF_OPENFLOW12

Add OFPUTIL_P_OF12 and NXFF_OPENFLOW12 for Open Flow 1.2

OFPUTIL_P_OF12_TID and in turn OFPUTIL_P_OF12_ANY is not provided as
OFPUTIL_P_OF12 supports the use of table ids in modify flow messages.
