i applied the patch0708, but i still met the problem.
when i tested the 64bytes frame with smartbits, in the beginning both the RX and TX of the system are OK. but after a while,the network card would not receive and transmit packets any more.
i checked the proc/ params, and found that when soft_reset_count increased one, the system would stop to receive packets for a while.
the code after patched is as follows. at what condition will soft_reset_count increase? and is there something incorrect when dealing with that? maybe the sp->cur_rx should be dealt?
if (!(status & RxComplete)) {
int intr_status;
unsigned long ioaddr = dev->base_addr;
unsigned long flags;
spin_lock_irqsave(&sp->lock,flags);
intr_status = inw(ioaddr + SCBStatus);
/* We check receiver state here because if
* we have to do soft reset,sp->cur_rx should
* point to an empty entry or something
* unexpected will happen
*/
if ((intr_status & 0x3c) != 0x10) {
if (speedo_debug > 4)
printk("No resource,reset\n");
speedo_rx_soft_reset(dev);
sp->soft_reset_count++;
}
spin_unlock_irqrestore(&sp->lock,flags);
break;
}
