38 * Dez 11 2004 V1.10 Kiszka Add RX ring buffer support
40 * This is the etherboot intel etherexpress Pro/100B driver.
42 * It was written from scratch, with Donald Beckers eepro100.c kernel
43 * driver as a guideline. Mostly the 82557 related definitions and the
44 * lower level routines have been cut-and-pasted into this source.
46 * The driver was finished before Intel got the NDA out of the closet.
47 * I still don't have the docs.
50 * Datasheet is now published and available from
51 * ftp://download.intel.com/design/network/manuals/8255X_OpenSDM.pdf
55 /* Philosophy of this driver.
59 * Using the pci.c functions of the Etherboot code, the 82557 chip is detected.
60 * It is verified that the BIOS initialized everything properly and if
61 * something is missing it is done now.
67 * The chip is then initialized to "know" its ethernet address, and to
68 * start recieving packets. The Linux driver has a whole transmit and
69 * recieve ring of buffers. This is neat if you need high performance:
70 * you can write the buffers asynchronously to the chip reading the
71 * buffers and transmitting them over the network. Performance is NOT
72 * an issue here. We can boot a 400k kernel in about two
73 * seconds. (Theory: 0.4 seconds). Booting a system is going to take
74 * about half a minute anyway, so getting 10 times closer to the
75 * theoretical limit is going to make a difference of a few percent. */
76 /* Not totally true: busy networks can cause packet drops due to RX
77 * buffer overflows. Fixed in V1.10 of this driver. [Kiszka] */
80 * Transmitting and recieving.
82 * We have only one transmit descriptor. It has two buffer descriptors:
83 * one for the header, and the other for the data.
84 * We have multiple receive buffers (currently: 4). The chip is told to
85 * receive packets and suspend itself once it ran on the last free buffer.
86 * The recieve (poll) routine simply looks at the current recieve buffer,
87 * picks the packet if any, and releases this buffer again (classic ring
88 * buffer concept). This helps to avoid packet drops on busy networks.
92 * The Etherboot framework moves the code to the 48k segment from
93 * 0x94000 to 0xa0000. There is just a little room between the end of
94 * this driver and the 0xa0000 address. If you compile in too many
95 * features, this will overflow.
96 * The number under "hex" in the output of size that scrolls by while
97 * compiling should be less than 8000. Maybe even the stack is up there,
98 * so that you need even more headroom.
101 /* The etherboot authors seem to dislike the argument ordering in
102 * outb macros that Linux uses. I disklike the confusion that this
103 * has caused even more.... This file uses the Linux argument ordering. */
