Subject: [PATCH bpf-next 0/3] Support UMEM chunk_size > PAGE_SIZE

This patchset adds AF_XDP support for chunk sizes > PAGE_SIZE.

The changes depend on the following commit recently applied to the bpf tree:
cc7df4813b149 ("xsk: Add missing overflow check in xdp_umem_reg")

Thanks to Magnus Karlsson for his initial feedback!

Kal Conley (3):
  xsk: Support UMEM chunk_size > PAGE_SIZE
  selftests: xsk: Use hugepages when umem->frame_size > PAGE_SIZE
  selftests: xsk: Add tests for 8K and 9K frame sizes
