[PATCH v3 26/46] hw/net/lan9118: use qemu_configure_nic_device()

Posted by David Woodhouse 10 months, 3 weeks ago

From: David Woodhouse <dwmw@amazon.co.uk>

Some callers instantiate the device unconditionally, others will do so only
if there is a NICInfo to go with it. This appears to be fairly random, but
preseve the existing behaviour for now.
