36 * Alteon Networks Tigon PCI gigabit ethernet driver for FreeBSD.
37 * Manuals, sample driver and firmware source kits are available
38 * from http://www.alteon.com/support/openkits.
40 * Written by Bill Paul <wpaul@ctr.columbia.edu>

42 * Columbia University, New York City
46 * The Alteon Networks Tigon chip contains an embedded R4000 CPU,
47 * gigabit MAC, dual DMA channels and a PCI interface unit. NICs
48 * using the Tigon may have anywhere from 512K to 2MB of SRAM. The
49 * Tigon supports hardware IP, TCP and UCP checksumming, multicast
50 * filtering and jumbo (9014 byte) frames. The hardware is largely
51 * controlled by firmware, which must be loaded into the NIC during
54 * The Tigon 2 contains 2 R4000 CPUs and requires a newer firmware
55 * revision, which supports new features such as extended commands,
56 * extended jumbo receive ring desciptors and a mini receive ring.
58 * Alteon Networks is to be commended for releasing such a vast amount
59 * of development material for the Tigon NIC without requiring an NDA
60 * (although they really should have done it a long time ago). With
61 * any luck, the other vendors will finally wise up and follow Alteon's
64 * The firmware for the Tigon 1 and 2 NICs is compiled directly into
65 * this driver by #including it as a C header file. This bloats the
66 * driver somewhat, but it's the easiest method considering that the
67 * driver code and firmware code need to be kept in sync. The source
68 * for the firmware is not provided with the FreeBSD distribution since
69 * compiling it requires a GNU toolchain targeted for mips-sgi-irix5.3.
71 * The following people deserve special thanks:
72 * - Terry Murphy of 3Com, for providing a 3c985 Tigon 1 board
74 * - Raymond Lee of Netgear, for providing a pair of Netgear
75 * GA620 Tigon 2 boards for testing
76 * - Ulf Zimmermann, for bringing the GA260 to my attention and
77 * convincing me to write this driver.
78 * - Andrew Gallatin for providing FreeBSD/Alpha support.
