Hi Alexey,
or do we want to allow using TST_USE_NETNS?
Kind regards,
Petr

to make testing faster.
NOTE: the default sleep 5s is needed for ssh based testing to prevent
link-flap errors on the switch. It can be lower down by user.

Hi Petr,
What about adding the option to change this value too for netns,
for example like this:
TST_TIMEOUT=1
if tst_net_use_netns; then
CHANGE_INTERVAL=${CHANGE_INTERVAL:-100ms}
else
CHANGE_INTERVAL=${CHANGE_INTERVAL:-5}
tst_is_int $CHANGE_INTERVAL && TST_TIMEOUT=$CHANGE_INTERVAL
fi
TST_TIMEOUT=$(((TST_TIMEOUT + 30) * MTU_CHANGE_TIMES))

That's indeed much better!
How about allow to overwrite CHANGE_INTERVAL even for netns?
i.e move tst_is_int $CHANGE_INTERVAL && TST_TIMEOUT=$CHANGE_INTERVAL
after the test (although it's unlikely anybody would use sec value for netns
and ms value for ssh):
# CHANGE_INTERVAL: The interval of the mtu change
TST_TIMEOUT=1
if tst_net_use_netns; then
CHANGE_INTERVAL=${CHANGE_INTERVAL:-100ms}
else
CHANGE_INTERVAL=${CHANGE_INTERVAL:-5}
fi
tst_is_int $CHANGE_INTERVAL && TST_TIMEOUT=$CHANGE_INTERVAL
TST_TIMEOUT=$(((TST_TIMEOUT + 30) * MTU_CHANGE_TIMES))
