    net: revert IPv6 traffic class and flow label fields
    
    The IPv6 header bitfields "version", "ds", "ecn", and "flow_label"
    are not organized correctly on little endian architectures.
    On little endian, a 32-bit bitfield is allocated from the least
    significant bit of the host order word, but "vtc_flow" is stored in
    network order. All four fields therefore read and write the wrong
    bits. For example, setting "version" to 6 writes 0x60 into the last
    byte of the word.
    
    "ds" and "flow_label" are not contiguous in memory on little endian,
    so no reordering of bitfields can express them.
    
    Reverted the patch introducing these bitfields.
    
    PS: There is a GCC attribute to fix this, but nothing similar is
    offered by Clang or MSVC:
    __attribute__((scalar_storage_order("big-endian")))
