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!
