    Rx: Correct AFS_NT40_ENV rx_GetIFInfo max MTU assignments
    On UNIX, the rx library values for rx_maxReceiveSize and
    rx_MyMaxSendSize are sent by the cache manager directly.
    In Windows, they are set by rx_GetIFInfo() which had two
    (1) The comparison of rx_maxReceiveSize and maxsize were
        reversed which prevented rx_maxReceiveSize from ever
        being set to the interface MTU.
    (2) rx_MyMaxSendSize was never assigned a value.
    As a result, two problems occurred.
    (1) The remote peer was never told about the local MTU.
    (2) The local peer ignores the MTU.
    From 1.3.60 to 1.5.33, OpenAFS for Windows installers
    provided a registry default RxMaxMTU of 1260.  This caused
    the cache manager to call rx_SetMaxMTU() which in turn set
    both rx_maxReceiveSize and rx_MyMaxSendSize in effect
    masking these errors.
