[Nfd-dev] NDNLP fragmentation design for UDP faces?

Hi,

I am looking at the code and looks like for Ethernet the
fragmentation/reassembly options are set here for multicast and
unicast, respectively:
https://github.com/named-data/NFD/blob/4d82692800314193b48d3dbb06cbecf168699a48/daemon/face/ethernet-factory.cpp#L247
https://github.com/named-data/NFD/blob/4d82692800314193b48d3dbb06cbecf168699a48/daemon/face/ethernet-channel.cpp#L201

If I am reading this correctly, it should be relatively easy to add
the same logic during UDP face creation. Is there anything else that
needs to be configured?

I also looked at the MTU issue:
https://redmine.named-data.net/issues/4005. I am not sure why PMTUD is
disabled for UDP faces or how much work it would be to enable it, so
pointers are appreciated.

Thanks.
