Subject:   sr-iov issues, reset_hw() failed with error -100
Message-ID:  <CANJ8om4_QnXU_4qywqAjrUW%2B25xNrt2nTE_ED7QQgfygLSqxzA@mail.gmail.com>

 Decided to do some testing with iovctl to see how sr-iov is coming along.
Currently when adding the vf's there are a couple errors, and the network
no longer function after iovctl is started. My guess is the reset_hw() call
that is failing. Any ideas why this call would fail? I tested this on both
ports, ix1 is detached and unused for this test, however inserting a cable
results in an unusable port. iovctl -Dd ix1 removes the vf's, however
functionality is still not restored without a system restart.
