Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

141 A dev_link_t structure has fields for most things that are needed
142 to keep track of a socket, but there will usually be some device
143 specific information that also needs to be kept track of. The
144 'priv' pointer in a dev_link_t structure can be used to point to
145 a device-specific private data structure, like this.
146
147 To simplify the data structure handling, we actually include the
148 dev_link_t structure in the device's private data structure.
149
150 A driver needs to provide a dev_node_t structure for each device
151 on a card. In some cases, there is only one device per card (for
152 example, ethernet cards, modems). In other cases, there may be
153 many actual or logical devices (SCSI adapters, memory cards with
154 multiple partitions). The dev_node_t structures need to be kept
155 in a linked list starting at the 'dev' field of a dev_link_t
156 structure. We allocate them in the card's private data structure,
157 because they generally shouldn't be allocated dynamically.
158
159 In this case, we also provide a flag to indicate if a device is
160 "stopped" due to a power management event, or card ejection. The
161 device IO routines can use a flag like this to throttle IO to a
162 card that is not ready to accept it.
