Subject: [PATCH 2/5] test/lib: Wait for kernel to free up ports used by iperf3 before reusing them
Date: Fri, 23 Sep 2022 02:53:24 +0200	[thread overview]
Message-ID: <20220923005327.1000042-3-sbrivio@redhat.com> (raw)
In-Reply-To: <20220923005327.1000042-1-sbrivio@redhat.com>

[-- Attachment #1: Type: text/plain, Size: 679 bytes --]

If we start another server on the same port right away, we might fail
to bind the port. A small delay appears to be needed -- I'm not
entirely sure why at this point.
