88 *	- Am79c961A PCnet-ISA II Jumperless Full-Duplex Single-Chip
89 *	  Ethernet Controller for ISA
90 *
91 *	- Am79c965A PCnet-32 Single-Chip 32-bit Ethernet Controller
92 *	  (for VESA and 486 local busses)
93 *
94 *	- Am79c970 PCnet-PCI Single-Chip Ethernet Controller for PCI
95 *	  Local Bus
96 *
97 *	- Am79c970A PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller
98 *	  for PCI Local Bus
99 *
100 *	- Am79c971 PCnet-FAST Single-Chip Full-Duplex 10/100Mbps
101 *	  Ethernet Controller for PCI Local Bus
102 *

104 *	  with OnNow Support
105 *
106 *	- Am79c973/Am79c975 PCnet-FAST III Single-Chip 10/100Mbps PCI
107 *	  Ethernet Controller with Integrated PHY

111 *
112 * Initialization block, transmit descriptor, and receive descriptor
113 * formats are described in two separate files:
114 *
115 *	16-bit software model (LANCE)		am7990reg.h
116 *
117 *	32-bit software model (ILACC)		am79900reg.h
118 *
119 * Note that the vast majority of the registers described in this file
120 * belong to follow-on chips to the original LANCE.  Only CSR0-CSR3 are
121 * valid on the LANCE.
