    rt2x00: Fix BUG_ON() with antenna handling · 6d64360a
    Ivo van Doorn authored
    With the new configuration handling, and more specifically
    splitting the configuration of the antenna from the normal
    configuration steps allowed a BUG_ON() to be triggered
    in the driver because the SW_DIVERSITY was send to the
    driver. This fixes that by catching the value early in
    rt2x00config.c and replacing it with a sensible value.
    This also fixes a problem where the antenna is not being
    initialized at all when the radio is enabled. Since it
    no longer is part of the mac80211 configuration the
    only place where rt2x00 configured it was the SW diversity
    handler. Obviously this is broken for all non-diversity
    hardware and breaks SW diversity due to a broken initialization.
    When the radio is enabled the antenna will be configured
    once as soon as the config() callback function is called.
