783 means: Tx Underrun Tx Idle Tx Packet Error Tx Descriptor Rx Packet Error Rx Descriptor Rx OK.
Hmm. I download the Documentation from National (http://www.national.com/pf/DP/DP83815.html), and the the tx burst size/fill threshold/drain threshold combination is invalid:
<<<<<<<< from natsemi.c: /* Configure the PCI bus bursts and FIFO thresholds. */ /* Configure for standard, in-spec Ethernet. */ np->tx_config = (1<<28) + /* Automatic transmit padding */ (1<<23) + /* Excessive collision retry */ (0x0<<20) + /* Max DMA burst = 512 byte */ (8<<8) + /* fill threshold = 256 byte */ 2; /* drain threshold = 64 byte */ writel(np->tx_config, ioaddr + TxConfig); >>>>>>>>>>>>
But: <<<<<<<< page 51 The MXDMA MUST NOT be greater than the Tx Fill Threshold >>>>>>>>>>
Could you try this setup? <<<<<<<< /* Configure the PCI bus bursts and FIFO thresholds. */ /* Configure for standard, in-spec Ethernet. */ np->tx_config = (1<<28) + /* Automatic transmit padding */ (1<<23) + /* Excessive collision retry */ (6<<20) + /* Max DMA burst = 128 byte */ (8<<8) + /* fill threshold = 256 byte */ 8; /* drain threshold = 256 byte */ writel(np->tx_config, ioaddr + TxConfig); >>>>>>>>
