It is basically * the same as the 21140 but with a few new features. The 21143 supports * three kinds of media attachments: * * o MII port, for 10Mbps and 100Mbps support and NWAY * autonegotiation provided by an external PHY. * o SYM port, for symbol mode 100Mbps support. * o 10baseT port. * o AUI/BNC port. * * The 100Mbps SYM port and 10baseT port can be used together in * combination with the internal NWAY support to create a 10/100 * autosensing configuration. * * Note that not all tulip workalikes are handled in this driver: we only * deal with those which are relatively well behaved. The Winbond is * handled separately due to its different register offsets and the * special handling needed for its various bugs. The PNIC is handled * here, but I'm not thrilled about it. * * All of the workalike chips use some form of MII transceiver support * with the exception of the Macronix chips, which also have a SYM port. * The ASIX AX88140A is also documented to have a SYM port, but all * the cards I've seen use an MII transceiver, probably because the * AX88140A doesn't support internal NWAY. */ #ifdef HAVE_KERNEL_OPTION_HEADERS #include "opt_device_polling.h" #endif #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #define DC_USEIOSPACE #include MODULE_DEPEND(dc, pci, 1, 1, 1); MODULE_DEPEND(dc, ether, 1, 1, 1); MODULE_DEPEND(dc, miibus, 1, 1, 1); /* * "device miibus" is required in kernel config.

The bug is that sometimes instead of * uploading one complete frame during reception, it uploads what looks * like the entire contents of its FIFO memory. The frame we want is at * the end of the whole mess, but we never know exactly how much data has * been uploaded, so salvaging the frame is hard. * * There is only one way to do it reliably, and it's disgusting. * Here's what we know: * * - We know there will always be somewhere between one and three extra * descriptors uploaded. * * - We know the desired received frame will always be at the end of the * total data upload. * * - We know the size of the desired received frame because it will be * provided in the length field of the status word in the last descriptor. * * Here's what we do: * * - When we allocate buffers for the receive ring, we bzero() them. * This means that we know that the buffer contents should be all * zeros, except for data uploaded by the chip. * * - We also force the PNIC chip to upload frames that include the * ethernet CRC at the end. * * - We gather all of the bogus frame data into a single buffer. * * - We then position a pointer at the end of this buffer and scan * backwards until we encounter the first non-zero byte of data. * This is the end of the received frame. We know we will encounter * some data at the end of the frame because the CRC will always be * there, so even if the sender transmits a packet of all zeros, * we won't be fooled. * * - We know the size of the actual received frame, so we subtract * that value from the current pointer location. This brings us * to the start of the actual received packet. * * - We copy this into an mbuf and pass it on, along with the actual * frame length. * * The performance hit is tremendous, but it beats dropping frames all * the time. */ #define DC_WHOLEFRAME (DC_RXSTAT_FIRSTFRAG | DC_RXSTAT_LASTFRAG) static void dc_pnic_rx_bug_war(struct dc_softc *sc, int idx) { struct dc_desc *cur_rx; struct dc_desc *c = NULL; struct mbuf *m = NULL; unsigned char *ptr; int i, total_len; uint32_t rxstat = 0; i = sc->dc_pnic_rx_bug_save; cur_rx = &sc->dc_ldata.dc_rx_list[idx]; ptr = sc->dc_pnic_rx_buf; bzero(ptr, DC_RXLEN * 5); /* Copy all the bytes from the bogus buffers. */ while (1) { c = &sc->dc_ldata.dc_rx_list[i]; rxstat = le32toh(c->dc_status); m = sc->dc_cdata.dc_rx_chain[i]; bcopy(mtod(m, char *), ptr, DC_RXLEN); ptr += DC_RXLEN; /* If this is the last buffer, break out. */ if (i == idx || rxstat & DC_RXSTAT_LASTFRAG) break; dc_discard_rxbuf(sc, i); DC_INC(i, DC_RX_LIST_CNT); } /* Find the length of the actual receive frame. */ total_len = DC_RXBYTES(rxstat); /* Scan backwards until we hit a non-zero byte. */ while (*ptr == 0x00) ptr--; /* Round off. */ if ((uintptr_t)(ptr) & 0x3) ptr -= 1; /* Now find the start of the frame. */ ptr -= total_len; if (ptr < sc->dc_pnic_rx_buf) ptr = sc->dc_pnic_rx_buf; /* * Now copy the salvaged frame to the last mbuf and fake up * the status word to make it look like a successful * frame reception. */ bcopy(ptr, mtod(m, char *), total_len); cur_rx->dc_status = htole32(rxstat | DC_RXSTAT_FIRSTFRAG); } /* * This routine searches the RX ring for dirty descriptors in the * event that the rxeof routine falls out of sync with the chip's * current descriptor pointer.
