I was able to see this in a single machine that has both 10 Gbit and 1 Gbit adapters.  If I use the 1 Gbit adapter it works fine, if I use the 10 Gbit adapter it fails (but kind of works as described above).  On 3 separate systems 1 Gbit works, and 3 other systems 10 Gbit fails.

Is the NIC driver the same for the 1 GbE and the 10 GbE NICs on Linux?

Do you have a Windows machine with a 10 GbE NIC that you could try?

Do you have a Mac with a 10 GbE NIC that you could try?
