The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

/*
|
|
* In NetBSD, the drivers are responsible for activating each
|
|
* function of a card and selecting the config to use. In
|
|
* 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.
