* In NetBSD, the drivers are responsible for activating each

* FreeBSD, all that's done automatically in the typical lazy
* way we do device resoruce allocation (except we pick the
* cfe up front). This is the biggest depature from the
* inherited NetBSD model, apart from the FreeBSD resource code.
*
* This seems to work well in practice for most cards.
* However, there are two cases that are problematic. If a
* driver wishes to pick and chose which config entry to use,
* then this method falls down. These are usually older
* cards. In addition, there are some cards that have
* multiple hardware units on the cards, but presents only one
* CIS chain. These cards are combination cards, but only one
* of these units can be on at a time.
*
* To overcome this limitation, while preserving the basic
* model, the probe routine can select a cfe and try to
* activate it. If that succeeds, then we'll keep track of
* and let that information persist until we attach the card.
* Probe routines that do this MUST return 0, and cannot
* participate in the bidding process for a device. This
* seems harsh until you realize that if a probe routine knows
* enough to override the cfe we pick, then chances are very
* very good that it is the only driver that could hope to
* cope with the card. Bidding is for generic drivers, and
* while some of them may also match, none of them will do
* configuration override.
