I haven't checked which of the patches, or some in other series caused
this on Clear Linux:

Yeah, fixed in https://patchwork.ozlabs.org/project/netdev/patch/20200805223359.32109-1-danieltimlee@gmail.com/

Thanks for headsup.
The fix will be pushed to bpf tree when net tree gets ffwd-ed to
Linus. Hopefully today.
