Network interfaces problem
Hi,

I have problems with my SCO unix network interfaces.
Intel integrated adapter was failing, so I installed new one - 3COM adapter into free PCI slot.
Installed driver using SCO Software manager - successfully
Added new Network adapter using SCO Network configuration manager - successfully
after that I checked using ifconfig -a
there was some loopback interfaces and - net0 -intel interface, and net1 -3com interface.
So I thought that everything is OK and removed intel adapter using Network configuration manager, after that things went wrong:
ifconfig -a displays only loopback interfaces.
3com driver is installed, 3com network adapter is added(Network configuration manager), but ifconfig -a don't display it!!!

So I thought that it's hardware problem - booted knoppix from cd - my 3com adapter is autodetected, up and running!

After that I tried all 'dumb' ways - rebooted, reinstalled(driver), changed apapter pci slot...- result is the same -driver - OK, adapter(Network configuration manager) - OK, "ifconfig -a" - no entries. By the way devices net0 and net1 are present(I asume net1 is my 3com adapter).

I'm newbe in unix so maybe I missing some 'obvious' step ?
How to force my 3com adapter(net1 ?) to apear in ifconfig list, and force it function corectlly ?

thank you
Vilius

ixgbe

IXGBE(4)						   BSD Kernel Interfaces Manual 						  IXGBE(4)

NAME

     ixgbe -- Intel(R) 10Gb Ethernet driver for the FreeBSD operating system

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device ixgbe

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_ixgbe_load="YES"

DESCRIPTION

     The ixgbe driver provides support for PCI 10Gb Ethernet adapters based on the Intel 82598EB Intel(R) Network Connections.	The driver sup-
     ports Jumbo Frames, MSIX, TSO, and RSS.

     For questions related to hardware requirements, refer to the documentation supplied with your Intel 10GbE adapter.  All hardware requirements
     listed apply to use with FreeBSD.

     Support for Jumbo Frames is provided via the interface MTU setting.  Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
     configures the adapter to receive and transmit Jumbo Frames.  The maximum MTU size for Jumbo Frames is 16114.

     This driver version supports VLANs.  For information on enabling VLANs, see ifconfig(8).

HARDWARE

     The ixgbe driver supports the following cards:

     o	 Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
     o	 Intel(R) 10 Gigabit XF SR/LR Server Adapter
     o	 Intel(R) 82598EB 10 Gigabit AF Network Connection
     o	 Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection

DIAGNOSTICS

     ixgbe%d: Unable to allocate bus resource: memory  A fatal initialization error has occurred.

     ixgbe%d: Unable to allocate bus resource: interrupt  A fatal initialization error has occurred.

     ixgbe%d: watchdog timeout -- resetting  The device has stopped responding to the network, or there is a problem with the network connection
     (cable).

SUPPORT

     For general information and support, go to the Intel support website at: http://support.intel.com.

     If an issue is identified with the released source code on the supported kernel with a supported adapter, email the specific information
     related to the issue to <freebsd@intel.com>.
