[PATCH v12 1/7] net/vmnet: add vmnet dependency and customizable option
Posted by Vladislav Yaroshchuk 4 months, 1 week ago
vmnet.framework dependency is added with 'vmnet' option
to enable or disable it. Default value is 'auto'.

vmnet features to be used are available since macOS 11.0,
corresponding probe is created into meson.build.
