If you are adding new code you should target net-next/main, which
has commit 18eabadd73ae ("vrf: Make pcpu_dstats update functions
available to other modules.") which adds those functions.

Have you rebased recently? Maybe your local clone of the tree is
stale?

FWIW: you can use `git format-patch --base=auto ...` to include base
tree information which can be helpful for identifying issues like
the above.
