With FreeBSD on MSI Z77 MPOWER motherboard, FreeBSD could never connect to Realtek 8111E/8168 Ethernet, then it was fixed some time around FreeBSD 10.2; subsequently FreeBSD relapsed to previous nonworking state in both current and stable/11 branches.
FreeBSD recognizes this Realtek chip, dhclient tries but can't make it. Linux, NetBSD and Haiku (R1Alpha4 from November 2012) connected.
MSI Z77 MPOWER motherboard also has a wireless Atheros 9271 quasi-USB chip (athn driver). Now NetBSD is allergic to this chip, won't boot unless I disable athn (userconf) or comment out athn in kernel config.
Previous to this turn of events, NetBSD could connect with this chip some of the time, but most of the time failed to load firmware.
For FreeBSD on this computer, I use Hiro H50191 USB wireless adapter (Realtek RTL8191SU chip) using rsu driver. This Hiro H50191 plugs in like a USB stick in contrast to Atheros 9271 which is an inseparable part of the motherboard. NetBSD has no hint of this driver (rsu).
But on recent update NetBSD-current i386 and amd64 installations, dhcpcd behavior has varied, even though it is the same 7.0-rc1 prerelease, so it must be something else besides dhcpcd itself.
So now I try direct Ethernet configuration without dhcpcd or dhclient and am glad to know how to do it and make the NetBSD installation usable again.

On my systems, trying to connect Ethernet seems consistent within a given OS installation on a particular system. Results have varied on NetBSD because of recent source-based updates.
I believe an Ethernet connection is usually released upon rebooting.
