Subject: [net-next 05/14] ice: Copy dcbx configuration only if mode is correct
Date: Fri, 23 Aug 2019 16:37:41 -0700 [thread overview]
Message-ID: <20190823233750.7997-6-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20190823233750.7997-1-jeffrey.t.kirsher@intel.com>
From: Michal Swiatkowski <michal.swiatkowski@intel.com>
In rebuild DCB desired_dcbx_cfg was copy to local_dcbx_cfg, but
if DCBX mode is IEEE desired_dcbx_cfg is not initialized by DCBX
config from FW. Change logic to copy config value only if mode is
set to CEE.
If driver copy desired_dcbx_cfg to local_dcbx_cfg in IEEE mode there
is problem with globr. System is frozen after two or more globr.
