Not sure what happen to my previous reply, most probably PEBKAC, sorry.

WRT this patch, note that the dup is harmless, as in the input path we
always use the mask and not the individual bit - vice versa in the
output path. Still the cleanup is worthy and patch LGTM.

Thank you for the patch!

It looks good to me too and MPTCP selftests are still happy with this patch.

Just one thing: please next time mention for which "net" tree this patch
is for. That's why you got one warning on Patchwork [1]. See [2] for
more details.

Here this patch is for -net: [PATCH net].
