From b3d2b014b259ba758d72d7026685091bde1cf2d6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 18 Jul 2023 21:38:09 +0200 Subject: [PATCH] RDMA/irdma: Fix building without IPv6 The new irdma_iw_get_vlan_prio() function requires IPv6 support to build: x86_64-linux-ld: drivers/infiniband/hw/irdma/cm.o: in function `irdma_iw_get_vlan_prio': cm.c:(.text+0x2832): undefined reference to `ipv6_chk_addr' Add a compile-time check in the same way as elsewhere in this file to avoid this by conditionally leaving out the ipv6 specific bits.
