Subject: [Qemu-devel] [patch 04/24] QEMU/KVM: return PCIDevice on net device init and record devfn
Date: Tue, 11 Mar 2008 17:11:55 -0300 [thread overview]
Message-ID: <20080311201417.512141001@localhost.localdomain> (raw)
In-Reply-To: 20080311201151.959635433@localhost.localdomain
[-- Attachment #1: return-pcidev --]
[-- Type: text/plain, Size: 9822 bytes --]
Change the PCI network drivers init functions to return the PCIDev, to
inform which slot has been hot-plugged.
Also record devfn on the NICInfo structure to locate for release
on hot-removal.
