Feature #4020
Updated by Junxiao Shi over 7 years ago
When creating a multicast Ethernet or UDP face, use Linux-specific API to detect whether the underlying network interface is ad hoc. If detection is successful, use that to set LinkType as either `LINK_TYPE_MULTI_ACCESS` or `LINK_TYPE_AD_HOC`. If detection is unsuccessful, keep using the value set in `face_system.ether.mcast_ad_hoc` and `face_system.udp.mcast_ad_hoc` config options.
