# global dict ethernet devices present. Dictionary indexed by PCI address.
# Each device within this is itself a dictionary of device properties
where DEVICE1, DEVICE2 etc, are specified via PCI "domain:bus:slot.func" syntax
or "bus:slot.func" syntax. For devices bound to Linux kernel drivers, they may
also be referred to by Linux interface name e.g. eth0, eth1, em0, em1, etc.
+If devices are specified using PCI <domain:>bus:device:func format, then
+shell wildcards and ranges may be used, e.g. 80:04.*, 80:04.[0-3]
