Author: bz Date: Sun Mar 17 09:31:09 2019 New Revision: 345241 URL: https://svnweb.freebsd.org/changeset/base/345241 Log: Fix legacy IP autoconfiguration. It seems my subconcious plan in r345088 to not only prefer IPv6 autoconf but to also slowly deteriorate legacy IP auto-configuration was uncovered way too early. In case IPv6 is a thing yet ipv6_autoconfif was not true, we would not bring up the interface yet tell the follow-up DHCPv4 configuration in ifconfig_up() that we did. So unless you were doing SYNCDHCP or IPv6 you would not get legacy-IP DHCPv4 configuration. I see multiple problems here: (a) people not yet using IPv6 (obviously a problem), and (b) the dhclient startup script not running dhclient in that case despite configured to do so (needs to be investigated seperately).
