34 * Alteon Networks Tigon PCI gigabit ethernet driver for FreeBSD.
35 * Manuals, sample driver and firmware source kits are available
36 * from http://www.alteon.com/support/openkits.

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

1057 * _and_ it has to be contiguous (unless you use the extended
1058 * jumbo descriptor format). Using malloc() all the time won't
1059 * work: malloc() allocates memory in powers of two, which means we

1066 * as external mbuf storage.

1072 * save space, we only actually allocate enough memory for 64 slots
