[Qemu-devel] [patch 02/19] qemu: return PCIDevice on net device init and record devfn |
Date: |

quilt/0.46-1 |
Change the PCI network drivers init functions to return the PCIDev, to
inform which slot has been hot-plugged.
Also record PCIDevice structure on NICInfo to locate for release on
hot-removal.
