Subject: dpif-netdev: Do not log error for EOPNOTSUPP return from netdev_recv().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7fa710e43fdf2dbf7fe41877cf73e04ccc4a7166;p=openvswitch

dpif-netdev: Do not log error for EOPNOTSUPP return from netdev_recv().

If a network device does not implement receiving packets, there is no point
in logging it as an error.
