Oh, I followed the commits from iproute2 until the new include files 
from (in this case) 5.11 pre rc1 had been updated (on 2020-12-24):

https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=2953235e61eb672bbdd2de84eb5b91c388f9a9b5

I thought the uapi updates in iproute2 are *always* pulled from the 
kernel and not from iprout2-next which was new to me.

Do you expect patches for iproute2-next when the relevant changes become 
available in linux-next then?

Even though I did not know about iproute2-next the patch is needed for 
the 5.11 kernel (as written in the subject).
