    12.04.2 server 10Gb intel ethernet fibre ixgbe not working

    I have a server with a 10Gb Ethernet fibre card. Looks like this in lspci:
    Code:
    82:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
    lsmod shows ixbge is loaded.
    Code:
    user@host:~$ lsmod |grep -E 'ixgbe|mdio|igb|ioat|dca'
    ioatdma                48178  48 
    ixgbe                 184924  0 
    mdio                   13808  1 ixgbe
    igb                   131190  0 
    dca                    15233  3 ioatdma,ixgbe,igb
    ifconfig sees the interfaces, one is configured:
    Code:
    eth0      Link encap:Ethernet  HWaddr 78:45:c4:aa:bb:bb  
              inet addr:10.10.10.23  Bcast:10.10.10.255  Mask:255.255.255.0

    The switch sees it's connected:
    Code:
    my-switch#show fiber-ports optical-transceiver 
    
                                       Output    Input

    But it never comes up properly, never shows packets.

    Do I need to recompile the intel driver? Is there a PPA with the latest driver? Is there something obvious I've missed? Any help appreciated.

    Re: 12.04.2 server 10Gb intel ethernet fibre ixgbe not working

    I have found that the fibre NICs don't come up until I run ethtool -r eth2. Then they work fine. I have added :

    up /sbin/ethtool -r eth2

    to /etc/network/interfaces and it now works fine. I shouldn't have to do that though.
