From cb816192d986f7596009dedcf2201fe2e5bc2aa7 Mon Sep 17 00:00:00 2001 From: Kittipon Meesompop Date: Tue, 15 Aug 2017 17:02:50 +0200 Subject: s390/qeth: fix using of ref counter for rxip addresses IP-address setting and removal are delayed when the device is not yet in state SOFTSETUP or UP. ref_counter has been implemented only for ip-address with type normal. In this patch ref_counter logic is also used for ip-address with type rxip to allow appropriate handling of multiple postponed rxip add and del calls.
