You can find it at [1]. Sometimes contiki devices don't make any header compression if it fits into a dataframe PDU. So this function have a check inside to see if we can pull. It doesn't really make sense there because we derefernce the byte before [2]. But it's okay for this moment, or not? I just want to don't use the skb_pull function. - Alex [1] https://github.com/linux-wpan/linux-net-next/commit/af2191adee6fc5010c3f32f4124367b9dba4502a#L0R1269 [2] https://github.com/linux-wpan/linux-net-next/commit/af2191adee6fc5010c3f32f4124367b9dba4502a#L0L1294 ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
