Re: Re: problem with eepro100 NAPI driver

[zhengchuanbo]

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;
      }
