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 * - Lite-On 82C115 (PNIC II): 59 * 60 * A clone of the Macronix MX98725, with the following differences: 61 * 62 * - Wake-On-LAN support 63 * - 128-bit multicast hash table rather than the 64 * standard 512-bit hash table 65 * - 802.3x flow control 66 * 67 * - Lite-On 82C168, 82C169 (PNIC): 68 * 69 * Pretty close, with only a few minor differences: 70 * 71 * - EEPROM is accessed completely differently. 72 * - MII is accessed completely differently. 73 * - No SIO facility (due to the above two differences). 74 * - GPIO interface is different than the 21140's. 75 * - Boards that lack PHYs use the internal NWay block 76 * and transciever. 77 * 78 * - Winbond 89C840F 79 * 80 * Less similar, but still roughly compatible (enough so 81 * that the driver can be adapted, at least): 82 * 83 * - Registers lack the pad word between them. 84 * - Instead of a setup frame, there are two station 85 * address registers and two multicast hash table 86 * registers (64-bit multicast hash table). 87 * - Only supported media interface is MII-over-SIO. 88 * - Different OPMODE register bits for various things 89 * (mostly media related). 90 * 91 * - ADMtek AL981 92 * 93 * Another pretty-close clone: 94 * 95 * - Wake-On-LAN support 96 * - Instead of a setup frame, there are two station 97 * address registers and two multicast hash table 98 * registers (64-bit multicast hash table). 99 * - 802.3x flow control 100 * - Only supported media interface is built-in PHY 101 * which is accessed through a set of special registers. 102 * - Not all registers have the pad word between them, 103 * but luckily, there are all AL981-specific registers, 104 * so this is easy to deal with. 105 * 106 * Some of the clone chips have different registers, and some have 107 * different bits in the same registers. These will be denoted by 108 * PMAC, PNICII, PNIC, WINB, and ADM in the register/bit names. 109 */ 110 111 /* 112 * Tulip buffer descriptor.
