Subject: OpenBSD: Don't spam syslog when cannot send NA
X-Git-Tag: v7.2.1~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fcc399eeb7bea265b285825f6b7b3b59e7796f43;p=thirdparty%2Fdhcpcd.git

OpenBSD: Don't spam syslog when cannot send NA

The error is "No route to host".
OpenBSD does not support IPv6 address sharing, so it's no biggie.
As such, only log an error when debugging.
