The basic EEH test ignores VFs since we the way the eeh_dev_break debugfs interface works means that if multiple VFs are enabled we may cause errors on all them them. However, we can work around that by only enabling a single VF at a time. This patch adds some infrastructure for finding SR-IOV capable devices and enabling / disabling VFs so we can exercise the VF specific EEH recovery paths. Two new tests are added, one for testing EEH aware devices and one for EEH un-aware VFs.
