This is a mock reproducer of this issue by faking a 20s delay in virtio-net after its link is up.
To enable that, user needs to build virtio-net with the hereby attached patch, and insert:
"echo 1 > /sys/module/virtio_net/parameters/droppkt"
in the /usr/sbin/kdump-config before the network dump procedure.
It'll introduce a 20s delay in packet transmission, causing the issue reported in this LP to be reproduced. This patch was developed in Bionioc 4.15.x kernel.
