We already do this in the page_changed handler, which is triggered when the
user is clicking between the storage/network/interface tabs. So you can click
to storage and then click back to interfaces to update this. That's obviously
sub optimal but then again so is all our handling of interface state change
behind virt-manager's back. What we need to properly fix this is actual async
event support for libvirt interfaces (not too hard) and netcf (more
difficult). Until then I'd rather just leave it as is then add an interface
specific poll call into the show() function
Thanks,
