[PATCH bpf-next 0/2] selftests: xsk: Add test case for packets at end of UMEM

[Kal Conley]

This patchset fixes a minor bug in xskxceiver.c then adds a test case
for valid packets at the end of the UMEM.

Kal Conley (2):
  selftests: xsk: Use correct UMEM size in testapp_invalid_desc
  selftests: xsk: Add test case for packets at end of UMEM

[PATCH bpf-next 1/2] selftests: xsk: Use correct UMEM size in testapp_invalid_desc

[Kal Conley]

Avoid UMEM_SIZE macro in testapp_invalid_desc which is incorrect when
the frame size is not XSK_UMEM__DEFAULT_FRAME_SIZE. Also remove the
macro since it's no longer being used.

I tried test_xsk.sh. The changed subtest runs ok, so applied.

I got failures from test_xsk.sh (even before this set) though. Are these 
expected or something missing in the environment like kconfig?

I fixed the other errors here and here (please apply those):
https://patchwork.kernel.org/project/netdevbpf/patch/20230403120400.31018-1-kal.conley@dectris.com/
https://patchwork.kernel.org/project/netdevbpf/patch/20230405082905.6303-1-kal.conley@dectris.com/

One is against bpf and one is against bpf-next (because someone told
me to move it). I guess they should both be applied to the same
branch, probably bpf?

They are all fixing a selftests, so applied both to bpf-next also. better but 
still has errors. The errors are down to 'fail:2' now:
