[ 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.
