Subject: 2.6.21rc7 e1000 media-detect oddness.

I booted up 2.6.21rc7 without an ethernet cable plugged in,
and noticed this..

e1000: 0000:02:00.0: e1000_probe: The EEPROM Checksum Is Not Valid
e1000: probe of 0000:02:00.0 failed with error -5

I plugged a cable in, did rmmod e1000;modprobe e1000, and got this..

e1000: 0000:02:00.0: e1000_probe: (PCI Express:2.5Gb/s:Width x1) 00:16:d3:3a:62:d3
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth0: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX
e1000: eth0: e1000_watchdog: 10/100 speed: disabling TSO

and it works fine..
Why would no cable make it think the EEPROM is invalid ?

I repeated this a few times, just to be sure it wasn't a fluke, and it
seems to happen 100% reproducably.
