From 8cebedb643832586162aa5313cae781173c1f81b Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Wed, 17 Jun 2020 16:54:53 +0200 Subject: s390/qeth: let isolation mode override HW offload restrictions When a device is configured with ISOLATION_MODE_FWD, traffic never goes through the internal switch. Don't apply the offload restrictions in this case. Fixes: c619e9a6f52f ("s390/qeth: don't use restricted offloads for local traffic") Signed-off-by: Julian Wiedmann Signed-off-by: David S.
