Description Marcin Mirecki 2020-09-08 09:20:15 UTC 
A eof error occurs randomly during SriovNetworkNodeStates lookup.

The test is performing a lookup to verify if the test environment is stable. The check is done at one second intervals for a few minutes, so for each test it can be hundreds or even tens of lookup calls. Once every while the lookup results in an eof error. The issue occurs only from within the tests (trying to reproduce it from cmd line was not successful), and as such is difficult to debug. 

The following PR is a workaround for the issue:
