Dear Ben.

FYI(For Your Information)
This is Naoto MATSUMOTO, Senior Researcher, SAKURA Internet.

We tried ethtool 3.5 on 40GbE NIC(Mellanox), it's result here.
-----------------------------------------------------------------------
# ./ethtool --version
ethtool version 3.5

# ./ethtool eth1
Settings for eth1:
        Supported ports: [ TP ]
        Supported link modes:   10000baseT/Full
        Supported pause frame use: No
        Supports auto-negotiation: No
        Advertised link modes:  10000baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: No
        Speed: 40000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: off
        MDI-X: Unknown

                               link ifdown
        Link detected: yes


Our 40GbE NIC Firmware/Dirver status are here.
-----------------------------------------------------------------------
Mellanox ConnectX HCA Ethernet driver v1.5.8.3 (June 2012)
Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]
Firmware Version: 2.10.800
-----------------------------------------------------------------------


And We were testing 10GbE(Intel) NIC and your 40GbE NIC in our lab
using ethtool with added some debug code.

-----------------------------------------------------------------------
# ./ethtool-p eth5 (10GbE NIC by Intel)
Settings for eth5:
        Supported ports: [ FIBRE ]
        Supported link modes:   10000baseT/Full

        mask == 5120 <--- ep->support number

# ./ethtool-p eth1 (40GbE NIC by Mellanox)
Settings for eth1:
        Supported ports: [ TP ]
        Supported link modes:   10000baseT/Full

        mask == 4224 <--- ep->support number
-----------------------------------------------------------------------

It's firmware problem I thinks. But Just Information for you ;-)
