  MFC r181270.
    The number of bits reserved for MSS in RealTek controllers is
    11bits. This limits the maximum interface MTU size in TSO case
    as upper stack should not generate TCP segments with MSS greater
    than the limit. Armed with this information, disable TSO if
    interface MTU is greater than the limit.
