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.

Sorry Thomas, I missed one important thing:

Your Signed-off-by line needs to go above the scissors ('---')
because when git applies your patch nothing below the scissors
is included in the patch description.

Welp, this seems to be due to a combination of me forgetting to add it,
b4 adding it below the scissors automatically and then failing to warn
about the missing sign-off.

I'll resend v2 with your tags. And will also remove the Cc: stable as
per net rules.

Thanks!

Thanks. Please be aware of the 24h rule.

BTW, if b4 is adding it then, maybe, you need to remove
it from the cover letter using b4 prep --edit-cover
