Description
In Ubuntu on Windows (Windows 10 Home, version 1709, build 16299.248), WiFi network interfaces are presented as "link/ieee802.11" instead of "link/ether". Such WiFi interfaces are capable of UDP multicast, as tested with netcat.
NetworkMonitor currently only recognizes "link/loopback" and "link/ether" interface types, as indicated in DEBUG logs. It should recognize "link/ieee802.11" as well.

- Project changed from NFD to ndn-cxx
- Subject changed from UDP multicast on ieee802.11 interfaces to Recognize IEEE802.11 interfaces on WSL
- Category changed from Faces to Network
- Priority changed from Normal to Low
- Target version set to Unsupported
UdpFactory is innocent. It only checks that the interface isn't loopback and that it supports multicast (as indicated by the interface flags). What you're seeing is likely caused by the fact that ndn-cxx's NetworkMonitor ignores all interfaces whose type is neither ARPHRD_ETHER nor ARPHRD_LOOPBACK. Normally, WiFi interfaces are ARPHRD_ETHER.
I have no idea what "link/ieee802.11" means, I guess it's ARPHRD_IEEE80211, but I need more info. Please attach a TRACE log of the ndn.NetworkMonitor module.

1520206522.605097 DEBUG: [ndn.NetworkMonitor] unhandled interface type 801
801 is ARPHRD_IEEE80211, which means WiFi interface in monitor mode. We shouldn't touch monitor interfaces (and in some/most cases they can't transmit anyway). If your interfaces are not in monitor mode, then Microsoft's implementation of netlink is broken, open a bug with them.
As far as NetworkMonitor is concerned, this behavior (ignoring ARPHRD_IEEE80211 interfaces) is intended.

Upstream reports that the WSL bug should be fixed in build 17627. Can you test again with that build?
