[realtek] Implementing set_mac_address for the rtl8139 driver?

I tried adding a mac_setting method like this:



static int rtl8139_set_eth_mac_addr(struct net_device *dev, void *p)
{
        struct sockaddr *addr=p;
        int i;
        long ioaddr = dev->base_addr;
    
        if (netif_running(dev)) {
                return -EBUSY;
        }
        memcpy(dev->dev_addr, addr->sa_data,dev->addr_len);

        for (i = 0; i < 6; i++) {
                outb(dev->dev_addr[i], ioaddr + MAC0 + i);
        }

        return 0;
}


But, it worked no better than the default which didn't try to poke
anything into the driver...


Here is some diags (at this point, I've run these commands):
	ifconfig eth1 down
	ifconfig eth1 hw ether 00:48:54:85:2F:BB
	ifconfig eth1 up

	(Tried to ping various different ways...didn't work.)
	(Set to promisc mode, pings started working immediately...)

	
NOTE:  The Station Addresses (RAM, I'm hoping), have some added
space around them for readability.

NOTE2:  I'm using source-based routing, and the ping command:
ping -I eth1 192.168.10.121 to ping my other node.
I watched the interfaces with tcpdump to verify packet activity
on the correct interface.
