This series modifies qemuFDPass to be a bit more convenient to use by
e.g. remembering the maximum fd set index currently used across libvirtd
restarts so that we can avoid having to pass the FDs before actually
constructing the device properties.
Along with that this code refactors the handling of FDs used for network
interfaces. There was a substantial amount of duplicated code with
plethora of helper variables and such. By converting to qemuFDPass
stored in the private data we can simplify the functions.
Peter Krempa (37):

qemu_fd: Remove error checking from qemuFDPassAddFD
qemuDomainAttachNetDevice: Use 'qemuFDPass' for the vdpa file
descriptor

qemu: slirp: Pass FDs to qemu via qemuFDPass in the network private
data
