Hi Kees,

Problem is my ARM machine don't have clang and iproute2 which is
keeping me from testing the bpf tail calls.

You should do the following to test it,.

1. tools/testing/selftests/bpf/
2. make
3. sudo ./test_progs

And, before testing, you have to do "make headers_install".
These tests are for tail calls with the attached patch. If its too
much work, Can you please upload your arm image so that I can test it?
I just need a good machine.
