Subject: dpif: Don't log warning for ENOENT with dpif_port_exists().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff_plain;h=bee6b8bc16b1c42fef8843cffe4d68b464cddadf

dpif: Don't log warning for ENOENT with dpif_port_exists().

The caller wants to know whether 'devname' is attached to 'dpif', and
ENOENT is a legitimate response to that not being the case.
