Subject: [net-next 08/16] ice: Fix corner case when switching from IEEE to CEE
Date: Wed, 4 Mar 2020 15:21:28 -0800 [thread overview]
Message-ID: <20200304232136.4172118-9-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20200304232136.4172118-1-jeffrey.t.kirsher@intel.com>
From: Avinash JD <avinash.dayanand@intel.com>
While testing DCB for a corner case in which mode is switched from IEEE to
CEE and pfc_ena bitmask unchanged then DCBX mode doesn't get updated.
This is happening because the function ice_dcb_get_mode() is called
in a "no change detected block" instead of "change detected block".
