It was caused by not executing i40e_reset_all_vfs due to flag __I40E_VF_DISABLE being set on PF. Because of this IAVF was never able to finish setup sequence never getting reset indication from PF. Changed test_and_set_bit __I40E_VF_DISABLE in i40e_sync_filters_subtask to test_bit and removed clear_bit. This function should not set this bit it should only check if it hasn't been already set.
