[ Upstream commit 6457595db9870298ee30b6d75287b8548e33fe19 ]
In rare cases, when the test environment is very slow, some userspace tests can fail because some expected events have not been seen.
Because the tests are expecting a long on-going connection, and they are not waiting for the end of the transfer, it is fine to make the connection longer. This connection will be killed at the end, after the verifications, so making it longer doesn't change anything, apart from avoid it to end before the end of the verifications
To play it safe, all endpoints tests not waiting for the end of the transfer are now sharing a longer file (128KB) at slow speed.
