Looking at the commit log, it's not the first time distfile is being 
silently rerolled:

commit 0fa0c820d6f179cf280a663437687f6fe1d4ab87
Author: Sunpoet Po-Chuan Hsieh <sunpoet at FreeBSD.org>
Date:   Sun Oct 4 14:12:56 2020 +0000

     Update distinfo: upstream rerolled the tarball

     - Bump PORTREVISION for package change

     Diff:           https://people.FreeBSD.org/~sunpoet/iperf-2.0.14a.diff

Looks like they did it again.
