From: Kittipon Meesompop Date: Tue, 15 Aug 2017 15:02:50 +0000 (+0200) Subject: s390/qeth: fix using of ref counter for rxip addresses X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb816192d986f7596009dedcf2201fe2e5bc2aa7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
