lspci -v will show more info including the kernel module used. "lspci -n | grep "02.00.00" will list the manufacture's id. You might need this to determine what kernel module should detect it.

The ifconfig command will list your network devices.

You will need to indicate which distro you are using. Debian based distros have one type of network configuration file. RPM based distos have another type, which is read in by the network startup script. These config files are were the network configuration is for a working device.

/sys/ is based on the contents of /proc/. If a device isn't present, maybe your kernel doesn't have the right kernel module loaded for it, or the kernel module, and kernel are to old to handle a newer device.
