Subject: dpif-linux: Avoid logging error on ENOENT in dpif_linux_is_internal_device().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=141d9ce465b9722fb9321c3d102238dd33507d79;p=openvswitch

dpif-linux: Avoid logging error on ENOENT in dpif_linux_is_internal_device().

ENOENT can be returned if the kernel module isn't loaded.  If that's the
case then we've already logged that and there's no point in logging it
again.
