Subject: [PATCH nf-next 04/19] selftest: netfilter: monitor result file sizes
Date: Wed,  3 May 2023 15:55:37 +0300	[thread overview]

When running nft_flowtable.sh in VM on a busy server we've found that
the time of the netcat file transfers vary wildly.

Therefore replace hardcoded 3 second sleep with the loop checking for
a change in the file sizes. Once no change in detected we test the results.

Nice side effect is that we shave 1 second sleep in the fast case
(hard-coded 3 second sleep vs two 1 second sleeps).
