From 4964c66fd49b2e2342da35358f2ff74614bcbaee Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Tue, 27 Feb 2018 18:58:15 +0100 Subject: Revert "s390/qeth: fix using of ref counter for rxip addresses" This reverts commit cb816192d986f7596009dedcf2201fe2e5bc2aa7. The issue this attempted to fix never actually occurs. l3_add_rxip() checks (via l3_ip_from_hash()) if the requested address was previously added to the card. If so, it returns -EEXIST and doesn't call l3_add_ip(). As a result, the "address exists" path in l3_add_ip() is never taken for rxip addresses, and this patch had no effect.
