Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Batch of fixes to the existing BPF flow dissector API to support
   calling BPF programs from the eth_get_headlen context (support for
   latter is planned to be added in bpf-next), from Stanislav.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
