This is what you would expect to get. The hardware is recognised but,
with no network cable attached, no address is obtained via the asked for
dhcp in /e/n/i. In dmesg you might see 'eth0: link is not ready'.

I'd put your previous, before rebooting observations down to some use
you made of ifconfig. For example, 'ifconfig eth0' followed
by 'ifconfig eth0 down' would explain eth0 having an address and not
being marked 'UP'.

This interface is not in /e/n/i. Something else is configuring it.
