pci-skeleton.c and several of Don's drivers actually do do something
else on TxUnderrun, twiddle DMA burst settings:
if ((intr_status & TxUnderrun)
&& (np->tx_config & TxThresholdField) !=
TxThresholdField) {
long ioaddr = dev->base_addr;
np->tx_config += TxThresholdInc;
writel(np->tx_config, ioaddr + TxMode);
np->stats.tx_fifo_errors++;
}
I wonder how feasible it is to do that on 3c59x hardware?
