Subject: [Intel-wired-lan] [PATCH S23 v4 09/15] ice: Do not always bring up PF VSI in ice_ena_vsi()
Date: Thu, 25 Jul 2019 01:55:35 -0700 [thread overview]
Message-ID: <20190725085541.55104-9-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20190725085541.55104-1-anthony.l.nguyen@intel.com>
During rebuild ice_ena_vsi() is called to recover the VSI state.
This function assumes the PF VSI is always to be enabled, however,
it's possible that during reset/rebuild the interface can be
brought down. If this occurs, we can attempt to bring up the PF
VSI on a downed interface which can lead to various crashes. If
the interface is not running, do not bring up the associated VSI.
