A dev_link_t structure has fields for most things that are needed

to keep track of a socket, but there will usually be some device

specific information that also needs to be kept track of. The

|
'priv' pointer in a dev_link_t structure can be used to point to

|
a device-specific private data structure, like this.
|
|
|
|
A driver needs to provide a dev_node_t structure for each device
|
|
on a card. In some cases, there is only one device per card (for
|
|
example, ethernet cards, modems). In other cases, there may be
|
|
many actual or logical devices (SCSI adapters, memory cards with
|
|
multiple partitions). The dev_node_t structures need to be kept
|
|
in a linked list starting at the 'dev' field of a dev_link_t
|
|
structure. We allocate them in the card's private data structure,
|
|
because they generally shouldn't be allocated dynamically.
|
|
|
|
In this case, we also provide a flag to indicate if a device is
|
|
"stopped" due to a power management event, or card ejection. The

device IO routines can use a flag like this to throttle IO to a
