Subject: [PATCH] testsuite/smokey: net: Ignore late or lost packets when running in VM
Date: Tue, 10 Aug 2021 12:17:27 +0200	[thread overview]
Message-ID: <ccc448d1-deb7-8c67-96b7-535e5b8b0176@siemens.com> (raw)

From: Jan Kiszka <jan.kiszka@siemens.com>

Do not fail the test if packets arrive late or are lost due to the
delays a VM, specifically an emulator like QEMU, may bring. Only if all
packets are lost, something is wrong and should be reported.

Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

This now replaces "testsuite/smokey: net_client: skip late packet error 
in vm mode" in next.
