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

Interrupt:42 Base address:0xc000
# route

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????
