    This a hidden option, which one should use with a lot of care.
    NO bug reports will be accepted if that option is enabled!
    You are warned.
    If you are 100% sure the headers memory space is always in a
    contiguous space, this will save stack usage and ROM in net core.
    This is a possible case when using IPv4 only, with
    NET_BUF_FIXED_DATA_SIZE enabled and NET_BUF_DATA_SIZE of 128 for
    instance.
