[Solved] ATL1E: 1000BaseT mode

Hi everyone,
I'm trying to get gigabit ethernet running on my EEE. The Attansic L1e is supposed to support it, and I know my router (Trendnet TEW-633GR) is not the problem as it works fine for my desktop. Autonegotiation results in 100mbit/s. I'm using the ATL1E driver included in the 2.6.30 kernel.

ethtool reports that this mode is not available, so I can't force it:

malstrond ~  $  sudo ethtool eth0
Settings for eth0:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
    Advertised auto-negotiation: Yes
    Speed: 100Mb/s
    Duplex: Full
    Port: Twisted Pair
    PHYAD: 0
    Transceiver: internal
    Auto-negotiation: on
    Supports Wake-on: pg
    Wake-on: d
    Current message level: 0x00000000 (0)
    Link detected: yes

mii-tool agrees:

malstrond ~  $  sudo mii-tool -v eth0
eth0: negotiated 100baseTx-FD flow-control, link ok
  product info: vendor 00:13:74, model 1 rev 9
  basic mode:   autonegotiation enabled
  basic status: autonegotiation complete, link ok
  capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
  advertising:  100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
  link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control

The last line would suggest that the driver isn't able to recognize my router advertising gigabit ethernet. Might it be possible that my router is at fault and somehow doesn't advertise correctly, in a way the driver doesn't understand?

The NIC:

malstrond ~  $  sudo lspci -vs 03:00.0
03:00.0 Ethernet controller: Attansic Technology Corp. L1e Gigabit Ethernet Adapter (rev b0)
    Subsystem: ASUSTeK Computer Inc. Device 8324
    Flags: bus master, fast devsel, latency 0, IRQ 27
    Memory at fbfc0000 (64-bit, non-prefetchable) [size=256K]
    I/O ports at ec00 [size=128]
    Capabilities: [40] Power Management version 2
    Capabilities: [48] MSI: Mask- 64bit+ Count=1/1 Enable+
    Capabilities: [58] Express Endpoint, MSI 00
    Capabilities: [6c] Vital Product Data
    Capabilities: [100] Advanced Error Reporting
    Capabilities: [180] Device Serial Number ff-8c-24-00-8d-c5-67-ff
    Kernel driver in use: ATL1E

Any ideas on a solution or where I could continue my research? Google doesn't really help as "Gigabit" is a part of the adapters name and "1000BaseT" seems to be a rarely used term.

Update: I think my NIC just doesn't have this feature. Marking as solved.

It's been more than a month, I think a bump is justified.

Re: [Solved] ATL1E: 1000BaseT mode

Anything in dmesg when the driver is loaded that might say why it doesn't want to enable gigabit speeds?

Looking at the driver code, the only way I see that these speeds wouldn't be available is if the card itself isn't advertising them in its registers.

No, dmesg doesn't seem to help:

I recently upgraded to a kernel 2.6.31 git build, which resulted in a different lspci output:

    Kernel driver in use: ATL1E

Altough the same driver is still in use, the chipset is identified as a different one and not all versions the new name applies to are capable of gigabit ethernet. I'm beginning to think that the EEE 1000H just doesn't have a controller with this capability and it was just incorrectly identified.
