What does the debug printout "LANSR" mean?

Hello all
I have been struggling to get the USRP2 to run for a few (long) days now
and today I decided to update the firmware to the latest UHD version.
When I connect the USRP2 to a 1GB switch I get the following debug
message

LANSR:0418
NOT LINK_GOOD

What does the numbers mean and what can be the reason for that?

(I am running Ubuntu 10.10 on a Lenovo X200 with GB Ethernet card)

Thanks!
