Linux-2.6.12-rc2v2.6.12-rc2

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!

+ *	Technical Card Details
+ *
+ *  All access to data is done with 16/8 bit transfers.  The transfer
+ *  method really sucks. You can only read or write one location at a time.
+ *
+ *  Also, the microcode for the card must be uploaded if the card does not have
+ *  the flashrom on board.  This is a 28K bloat in the driver when compiled
+ *  as a module.
+ *
+ *  Rx is very simple, status into a ring of descriptors, dma data transfer,
+ *  interrupts to tell us when a packet is received.
+ *
+ *  Tx is a little more interesting. Similar scenario, descriptor and dma data
+ *  transfers, but we don't have to interrupt the card to tell it another packet
+ *  is ready for transmission, we are just doing simple memory writes, not io or mmio
+ *  writes.  The card can be set up to simply poll on the next
+ *  descriptor pointer and when this value is non-zero will automatically download
+ *  the next packet.  The card then interrupts us when the packet is done.

+ *	and then point the end of the ring to our current position and point our current
+ *	position to 0, therefore making the current position the last position on the ring.
+ *	The last position on the ring therefore loops continually loops around the rx ring.
+ *	
+ *	rx_ring_tail is the position on the ring to process next. (Think of a snake, the head 
+ *	expands as the card adds new packets and we go around eating the tail processing the
+ *	packets.)
