5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <thomas.weissschuh@xxxxxxxxxxxxx>
[ 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.
Fixes: a7a29f9c361f ("net: ipv6: add rpl sr tunnel")
