[PATCH iproute2 v2 0/2] tests: fix issues in autopkgtest environment

Hi,
while working on Debian bug [1] and the Ubuntu counterpart of it
I found that the tests can throw a broken pipe warning.

I kept the associated check-and-retry of the length separate to
discuss the changes individually - feel free to squash them on
commit if preferred.

*Updates in v2*
tag with --subject-prefix='PATCH iproute2' to trigger the right
review queues in patchwork as requested by Luca Bocassi.
