[PATCH 0/2] Network device docs/iterator fixes
Two things noticed when reviewing the series for 'usb-net' device.

Since libvirt now tries to interpret network device models (unless an unknow model is used) the documentation didn't make a good job specifying what is supported.

Rework 'virDomainUSBDeviceDefForeach' to use virDomainDeviceInfoIterate instead of open-coding all iterators. To achieve this 'virDomainDeviceIsUSB' needs to be fixed as it didn't properly handle 'sound', 'fs', 'chr', 'ccid', and 'net usb devices.
