[eepro100] eth0: can't fill rx buffer (force 1)!

[NortonNg]

   I am using eepro100 for Intel 82559 chip NIC (but the driver said that it
was 82557 ), Redhat 7.0 Kernel 2.2.17 (patched from 2.2.16). After I do some
modification in dev.c for my packet dispatcher, when i run the nttcp 
(performance benchmark) several times (about transfered 400mega bits), 
both the gateway system will crash !!  my configuration is below..
  
  hostA<----->(eth1)IPSec gatewayA(eth0)<--->(eth0)IPSec GatewayB<-->hostB

 the error messages of IPSec gateway A are:

eth0: can't fill rx buffer (force 1)!
eth0: can't fill rx buffer (force 1)!
eth0: can't fill rx buffer (force 1)!
eth0: can't fill rx buffer (force 1)!
.....
....
eth1: card reports no resources
...
..
VM: do_try_to_free_pages failed for kswapd
VM: do_try_to_free_pages failed for kswapd
VM: do_try_to_free_pages failed for kswapd
VM: do_try_to_free_pages failed for kswapd
.....
	Sometimes when the "VM: do_try_to_free_pages.." messages are not occur,
i can restart eth1 of gateway A by ping hostA from gateway A.

my modified dev.c are here...

void net_bh(void )
{
...
..
  while( !skb_queue_empty(&backlog))
  {
    ...
    ...
    type = skb->protocol;

    //my part begin..
    if( something )
    {
       memcpy(skb->mac.ethernet->h_dest , my_dest_mac , 6);//dest card addr
	   memcpy(skb->mac.ethernet->h_source, my_src_mac, 6); //my card address
	   offset = (skb->data) - (skb->mac.raw);
	   skb_push( skb , offset ); 
	   skb->nh.raw   = skb->data + ETH_HLEN;
	   skb->priority = 1;
	   dev_queue_xmit(skb);  	
       goto skip_label;
    }
    //end of my part.

	handle_bridge(skb,type);
...
skip_label:
 } //end of loop
 ....
 ...

}
