Sorry, but it does not compile correctly if you define CONFIG_SIS190_NO_DELAY.

So it works.

It still do not work :

I compared sis190_rx_interrupt() in old and new driver, and i tried :

As you can see, no more RX errors, but the network script failed to establish the link.

On the other box (dhcp server) :
#dmesg
...

I also tried without dhcp :
# ifconfig

          RX bytes:4148 (4.0 KiB)  TX bytes:1806 (1.7 KiB)
          Interrupt:10 Base address:0xbeef

ping failed both sides, though RX and TX counters were incremented.
