It has GPR 51 * and MII media, and a GPIO facility, and uses the ISV 52 * SROM format (or, at least, should, because of the GPIO 53 * facility). The 98713A has MII, no GPIO facility, and 54 * an internal NWay block. The 98715, 98715A, and 98725 55 * have only GPR media and the NWay block. The 98715, 56 * 98715A, and 98725 support power management. 57 * 58 * The 98715AEC adds 802.3x flow Frame based Flow Control to the 59 * 98715A. 60 * 61 * - Lite-On 82C115 (PNIC II): 62 * 63 * A clone of the Macronix MX98725, with the following differences: 64 * 65 * - Wake-On-LAN support 66 * - 128-bit multicast hash table rather than the 67 * standard 512-bit hash table 68 * - 802.3x flow control 69 * 70 * - Lite-On 82C168, 82C169 (PNIC): 71 * 72 * Pretty close, with only a few minor differences: 73 * 74 * - EEPROM is accessed completely differently. 75 * - MII is accessed completely differently. 76 * - No SIO facility (due to the above two differences). 77 * - GPIO interface is different than the 21140's. 78 * - Boards that lack PHYs use the internal NWay block 79 * and transceiver. 80 * 81 * - Winbond 89C840F 82 * 83 * Less similar, but still roughly compatible (enough so 84 * that the driver can be adapted, at least): 85 * 86 * - Registers lack the pad word between them. 87 * - Instead of a setup frame, there are two station 88 * address registers and two multicast hash table 89 * registers (64-bit multicast hash table). 90 * - Only supported media interface is MII-over-SIO. 91 * - Different OPMODE register bits for various things 92 * (mostly media related). 93 * 94 * - ADMtek AL981 95 * 96 * Another pretty-close clone: 97 * 98 * - Wake-On-LAN support 99 * - Instead of a setup frame, there are two station 100 * address registers and two multicast hash table 101 * registers (64-bit multicast hash table). 102 * - 802.3x flow control 103 * - Only supported media interface is built-in PHY 104 * which is accessed through a set of special registers. 105 * - Not all registers have the pad word between them, 106 * but luckily, there are all AL981-specific registers, 107 * so this is easy to deal with. 108 * 109 * - ADMtek AN983 and AN985 110 * 111 * Similar to the ADMtek AL981, but with a few differences. 112 * 113 * - Xircom X3201-3 114 * 115 * CardBus 21143 clone, with a few differences: 116 * 117 * - No MicroWire SROM; Ethernet address must come 118 * from CIS. 119 * - Transmit buffers must also be 32-bit aligned. 120 * - The BUSMODE_SWR bit is not self-clearing. 121 * - Must include FS|LS in setup packet descriptor. 122 * - SIA is not 21143-like, and all media attachments 123 * are MII-on-SIO. 124 * 125 * - Davicom DM9102 and DM9102A 126 * 127 * Pretty similar to the 21140A, with a few differences: 128 * 129 * - Wake-On-LAN support 130 * - DM9102 has built-in 10/100 PHY on MII interface. 131 * - DM9102A has built-in 10/100 PHY on MII interface, 132 * as well as a HomePNA 1 PHY on an alternate MII 133 * interface (selected by clearing OPMODE_PS). 134 * - The chip has a bug in the transmit DMA logic, 135 * requiring that the packet be comprised of only 136 * one DMA segment. 137 * - The bus interface is buggy, and the BUSMODE register 138 * must be initialized to 0. 139 * - There seems to be an interrupt logic bug, requiring 140 * that interrupts be disabled on the chip during the 141 * interrupt handler. 142 * 143 * Some of the clone chips have different registers, and some have 144 * different bits in the same registers. These will be denoted by 145 * PMAC, PNICII, PNIC, DM, WINB, and ADM in the register/bit names. 146 */ 147 148 /* 149 * Tulip buffer descriptor.
