Re: [libvirt] [PATCHv3] replace 'if' type conditions with 'switch' for VIR_NETWORK_FORWARD_

Signed-off-by: Shi Lei <shilei.massclouds(a)gmx.com&gt; --- v2 here: https://www.redhat.com/archives/libvir-list/2018-July/msg01423.html since v2: - typecast def->forward.type to virNetworkForwardType explicitly in all the switches rather than change its type to enum in the struct definition v1 here: https://www.redhat.com/archives/libvir-list/2018-July/msg01314.html since v1: - Change the type declaration of _virNetworkForwardDef.type from int to virNetworkForwardType - use the default case to report out of range error with virReportEnumRangeError
