Subject: ofp-util: Make ofputil_encode_hello() return a message with correct length.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff_plain;h=1804d25a21dcdec83437ab1ebf9daf683d7e50da

ofp-util: Make ofputil_encode_hello() return a message with correct length.

This doesn't fix a visible bug, because code to send OpenFlow messages
updates the length itself, but it still seems like the right thing to do.
