Author: bz Date: Sun Jan 12 17:41:09 2020 New Revision: 356662 URL: https://svnweb.freebsd.org/changeset/base/356662 Log: nd6_rtr: constantly use __func__ for nd6log() Over time one or two hard coded function names did not match the actual function anymore. Consistently use __func__ for nd6log() calls and re-wrap/re-format some messages for consitency.
