x86: setup netdev paths for MX100

Browse Source 
The Meraki MX100 has ten 1000BASE-T and 2 SFP ethernet ports through
3, 4-port PCIe devices. The default enumeration of these network
devices' names does not correspond to their labeling. Fix this by
explicitly naming the devices, mapping against their sysfs path.

Note that these default network names can only be up to 8 characters,
because we can have up to 8 characters of modifiers (e.g. ^br-,
.4096$), and because the maximum network interface name is 16
characters long.
