With https://github.com/RIOT-OS/RIOT/pull/11596 and
https://github.com/RIOT-OS/RIOT/pull/11623 merged, fragmentation is
supported by RIOT's default network stack, GNRC.

* Does RIOT support IPv4? If so, does it support fragmentation in IPv4?

GNRC does not support IPv4. However you can use LwIP as an alternative.
AFAIK it supports fragmentation, but I am not 100% sure.

Might I ask what you need fragmentation for?
