	Hi, I'm using R5, it works great, but the ethernet hardware is not
responding ie:

	during the boot precess the eth is recognized as
	eth0: BMAC+ at 00:50:e4:7a:37:51
	after booting I issue:

# ifconfig eth0 192.168.3.2 broadcast 192.168.3.255 netmask  255.255.255.0
# ifconfig eth0
	eth0  Link encap: Ethernet  HWaddr 00:50:e4:7a:37:51
              inet addr: 192.168.3.40 Bcast:192.168.3.255 Mask:255.255.255.0
              UP BROADCAST RUNNING MULTICAST MTU: 1500 Metric: 1
              RX packets:0 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:100
              Interrupt:42 Base address:0xc000

# route
Kernel IP routing table
Destination     GW     GenMask          Flags Metric  Ref Use Iface
192.168.3.40    *      255.255.255.255  UH    0       0   0   eth0
192.168.3.0     *      255.255.255.0    U     0       0   0   eth0
127.0.0.0       *      255.0.0.0        U     0       0   0   lo

So the net is ok but when i try to ping any box in the net nothing
happends:

# ping -c 5 192.168.3.1
PING 192.168.3.1 (192.168.3.1): 56 data bytes

--- 192.168.3.1 ping statistics ---
5 packets transmited, 0 received, 100% packet loss

#ifconfig eth0
  XXX --- Same as before but
  RX packets:0 errors:0 dropped:0 overruns:0 frame:0
  TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

Then I guess that no packets were efectively transmited by the kernel eth
driver. Why?? What wrong?? There is other things yet, after boot
/dev/interrupts says:
     CPU0
XX:  XXX
32:     0     PMAC-PIC    BMAC-txdma
33:     0     PMAC-PIC    BMAC-rxdma
42:     0     PMAC-PIC    BMAC-misc

after the ping the interrupts remains as before so no interrupts were
handled by the driver, well if no packets were TX as i guess no intr were
generated that coherent. but if I issue:

#ifconfig eth0 down
#ifconfig eth1 up
#ifconfig eth0
XXX --- same as before
RX packets:0 errors:1 dropped:1 overruns:0 frame:1
TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
XXX --- same as before

why r RX errors? and why i try to TX 1 packet??

Any ideas why is this appening to me????
