Subject: [net-next v2 07/15] ice: Fix corner case when switching from IEEE to CEE
Date: Tue, 10 Mar 2020 13:45:26 -0700	[thread overview]
Message-ID: <20200310204534.2071912-8-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20200310204534.2071912-1-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".
