    Subject[PATCH] net/wireless: CFG80211_WEXT_EXPORT requires wireless extensions
    Date
    The CFG80211_WEXT_EXPORT symbol is selected by two drivers that
    make direct use of compat handlers for the wireless ioctls.
    However, this has no effect when the wireless extensions themselves
    are disabled, and results in a link error:

    ERROR: "cfg80211_wext_giwrts" [drivers/net/wireless/orinoco/orinoco.ko] undefined!
    ERROR: "cfg80211_wext_siwfrag" [drivers/net/wireless/orinoco/orinoco.ko] undefined!
    ERROR: "cfg80211_wext_giwname" [drivers/net/wireless/ipw2x00/ipw2200.ko] undefined!

    This changes the Kconfig logic so that CFG80211_WEXT can not
    be disabled when CFG80211_WEXT_EXPORT is set.

    Drivers should select this option if they require cfg80211's
    wext compatibility symbols to be exported.
