Subject: ch: interface: correctly update nicindexes
X-Git-Tag: v10.7.0-rc2~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a44f786252d3de285605707fe8740eb89ba6699;p=thirdparty%2Flibvirt.git

ch: interface: correctly update nicindexes

Originally nicindexes were updated only for VIR_DOMAIN_NET_TYPE_BRIDGE
and VIR_DOMAIN_NET_TYPE_DIRECT. The mentioned commit adds support for
NAT network mode and changes the code to update nicindexes for
VIR_DOMAIN_NET_TYPE_ETHERNET and VIR_DOMAIN_NET_TYPE_NETWORK as well.

It doesn't work as intended and after the change nicindexes are updated
only for VIR_DOMAIN_NET_TYPE_ETHERNET and VIR_DOMAIN_NET_TYPE_NETWORK.
