It has GPR * and MII media, and a GPIO facility, and uses the ISV * SROM format (or, at least, should, because of the GPIO * facility). The 98713A has MII, no GPIO facility, and * an internal NWay block. The 98715, 98715A, and 98725 * have only GPR media and the NWay block. The 98715, * 98715A, and 98725 support power management. * * - Lite-On 82C115 (PNIC II): * * A clone of the Macronix MX98725, with the following differences: * * - Wake-On-LAN support * - 128-bit multicast hash table rather than the * standard 512-bit hash table * - 802.3x flow control * * - Lite-On 82C168, 82C169 (PNIC): * * Pretty close, with only a few minor differences: * * - EEPROM is accessed completely differently. * - MII is accessed completely differently. * - No SIO facility (due to the above two differences). * - GPIO interface is different than the 21140's. * - Boards that lack PHYs use the internal NWay block * and transciever. * * - Winbond 89C840F * * Less similar, but still roughly compatible (enough so * that the driver can be adapted, at least): * * - Registers lack the pad word between them. * - Instead of a setup frame, there are two station * address registers and two multicast hash table * registers (64-bit multicast hash table). * - Only supported media interface is MII-over-SIO. * - Different OPMODE register bits for various things * (mostly media related). * * - ADMtek AL981 * * Another pretty-close clone: * * - Wake-On-LAN support * - Instead of a setup frame, there are two station * address registers and two multicast hash table * registers (64-bit multicast hash table). * - 802.3x flow control * - Only supported media interface is built-in PHY * which is accessed through a set of special registers. * - Not all registers have the pad word between them, * but luckily, there are all AL981-specific registers, * so this is easy to deal with. * * - Xircom X3201-3 * * CardBus 21143 clone, with a few differences: * * - No MicroWire SROM; Ethernet address must come * from CIS. * - Transmit buffers must also be 32-bit aligned. * - The BUSMODE_SWR bit is not self-clearing. * - Must include FS|LS in setup packet descriptor. * - SIA is not 21143-like, and all media attachments * are MII-on-SIO. * * - Davicom DM9102 and DM9102A * * Pretty similar to the 21140A, with a few differences: * * - Wake-On-LAN support * - DM9102 has built-in 10/100 PHY on MII interface. * - DM9102A has built-in 10/100 PHY on MII interface, * as well as a HomePNA 1 PHY on an alternate MII * interface (selected by clearing OPMODE_PS). * - The chip has a bug in the transmit DMA logic, * requiring that the packet be comprised of only * one DMA segment. * - The bus interface is buggy, and the BUSMODE register * must be initialized to 0. * - There seems to be an interrupt logic bug, requiring * that interrupts be disabled on the chip during the * interrupt handler. * * Some of the clone chips have different registers, and some have * different bits in the same registers. These will be denoted by * PMAC, PNICII, PNIC, DM, WINB, and ADM in the register/bit names. */ /* * Tulip buffer descriptor.
