and so on.

Those symbols are not defined anywhere.

The problem is due to a conflict with commit 348059313 (net: filter: get rid of BPF_S_*
enum), which removed those definitions.

Yep, it seems both got in this merge window from different trees. Don't have mips, but
I'll have a look, and send you a patch.

Could you give the attached patch a try?

Thanks,

Daniel
