38 * Alteon Networks Tigon PCI gigabit ethernet driver for OpenBSD.

45/*
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
52 * initialization.
53 *
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 descriptors and a mini receive ring.
57 *
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
62 * stellar example.
63 *
64 * The following people deserve special thanks:
65 * - Terry Murphy of 3Com, for providing a 3c985 Tigon 1 board
66 * for testing
67 * - Raymond Lee of Netgear, for providing a pair of Netgear
68 * GA620 Tigon 2 boards for testing
69 * - Ulf Zimmermann, for bringing the GA260 to my attention and
70 * convincing me to write this driver.
71 * - Andrew Gallatin for providing FreeBSD/Alpha support.
