From a3e83a402a736962f6969a9b319072babc0ffa8b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Mon, 16 Sep 2024 20:57:13 +0200 Subject: [PATCH] net: ipv6: select DST_CACHE from IPV6_RPL_LWTUNNEL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit 93c21077bb9ba08807c459982d440dbbee4c7af3 ] The rpl sr tunnel code contains calls to dst_cache_*() which are only present when the dst cache is built. Select DST_CACHE to build the dst cache, similar to other kconfig options in the same file. Compiling the rpl sr tunnel without DST_CACHE will lead to linker errors.
