"""Get NGPF device ids
NGPF has a /topology/deviceGroup -count attribute that is used to set the devices per port
Any NGPF class that has an operation that requires a list of session indices will have a GetDeviceIds method generated for it that calls into this method
All parameters will be optional and defaulted to None
The first parameter will always be a PortNames parameter defaulted to None
This method will evaluate all non None criteria for matches
e.g. System is configured with the following:
20 vports using the default generated names
2 topology with 10 vports assigned to each
User wants to send arp on topology 1 only on ports 1 and 8
ivp4_obj.SendArp(ipv4_obj.GetDeviceIds(PortName='^(Ethernet - 001|Ethernet - 008)$'))
1. Find the starting topology reference by walking the href back to topology
2. Find the starting index range based on the PortName
2.a all other matches will be constrained by this starting index range
Returns:
list: a list of numeric sessionindices
