--- Comment #3 from commit-h...@freebsd.org --- A commit references this bug: Author: kevans Date: Thu Jul 23 03:24:35 UTC 2020 New revision: 363442 URL: https://svnweb.freebsd.org/changeset/base/363442 Log: MFC r363244: ether_ifattach: set mtu before calling if_attach() if_attach() -> if_attach_internal() will call if_attachdomain1(ifp) any time an ethernet interface is setup *after* SI_SUB_PROTO_IFATTACHDOMAIN/SI_ORDER_FIRST. This eventually leads to nd6_ifattach() -> nd6_setmtu0() stashing off ifp->if_mtu in ndi->maxmtu *before* ifp->if_mtu has been properly set in some scenarios, e.g., USB ethernet adapter plugged in later on. For interfaces that are created in early boot, we don't have this issue as domains aren't constructed enough for them to attach and thus it gets deferred to domainifattach at SI_SUB_PROTO_IFATTACHDOMAIN/SI_ORDER_SECOND *after* the mtu has been set earlier in ether_ifattach().
