If that means doing up to 10 retries and stopping on the first success,
then yes, that's probably fine. I'd rather not add significant extra
latency here for the success case, but it is fine to make that take
longer if the broadcast frames do not get through and the test case
would fail anyway.

Please also note that there are couple of cases where
hwsim_utils.test_connectivity() is used for negative testing, i.e.,
there is not supposed to be connectivity and the test case fails if that
function does not raise an exception. Doing 10 retries there should
work, but it will add some latency. That said, I think it is justifiable
to do that for the non-hwsim case without more complexity since there
are only couple of such negative testing cases. Though, I'd be fine with
adding a parameter to the function to indicate if it is used for the
negative case so that the retries could be avoided.
