    bnxt_en: Query FW parameters when the CAPS_CHANGE bit is set

    Newer FW can set the CAPS_CHANGE flag during ifup if some capabilities
    or configurations have changed.  For example, the CoS queue
    configurations may have changed.  Support this new flag by treating it
    almost like FW reset.  The driver will essentially rediscover all
    features and capabilities, reconfigure all backing store context memory,
    reset everything to default, and reserve all resources.
