Daniel Borkman says: ==================== pull-request: bpf 2018-03-29 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix nfp to properly check max insn count while emitting instructions in the JIT which was wrongly comparing bytes against number of instructions before, from Jakub. 2) Fix for bpftool to avoid usage of hex numbers in JSON output since JSON doesn't accept hex numbers with 0x prefix, also from Jakub. ==================== Signed-off-by:
