[ovs-dev] [PATCH] ofproto-dpif-xlate: Lower missing netdev_max_backlog from WARN to INFO.

[Ben Pfaff]

In a network namespace, /proc/sys/net/core/netdev_max_backlog is not
present, so people running OVS inside Docker will always get a log message
here.  That's not important enough to rise to a WARN level that causes
tests to fail, especially since the default value is rarely changed (and
wouldn't normally be lowered), so reduce the log leve for this to INFO.
