network_device_info is too crude in categorising devices found by lspci

network_device_info, as used by networking/detect, uses the very crude logic that if a device is displayed as 'Ethernet Controller' in lspci, then it is in fact an ethernet controller. Due to stupidity in some drivers, some wireless cards show as 'Ethernet Controller' and have an interface name of eth1 for example. The logic of the script should be expanded to use more definite criteria.

One possibility is to take advantage of the udev parser to find the network devices. This does a better job of categorising them already and is used by other parts of Checkbox
