[Ndn-interest] [EXT] NDN Chunks larger files

[Junxiao Shi]

Hi Hahns

ndnputchunks by default creates Data packets of about 5KB, larger than
typical Ethernet MTU. This in turn causes IPv4 fragmentation.
If the WSL computer is the consumer, you need to add a rule in Windows
firewall to allow IPv4 fragments. Otherwise, packets cannot reach WSL
container.

Yours, Junxiao
