Subject: [net-next 09/15] ice: Do not always bring up PF VSI in ice_ena_vsi()
Date: Fri,  9 Aug 2019 11:31:33 -0700	[thread overview]
Message-ID: <20190809183139.30871-10-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20190809183139.30871-1-jeffrey.t.kirsher@intel.com>

From: Tony Nguyen <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.
