Ok, I have determined that my problem lies in user-land, not
the kernel.  Using the same kernel, but with a more elaborate
start-up scripts/root filesystem (those from DENX ELDK-1.0)
it works fine.

Using my minimal rootfs, with busybox, tinylogin, it doesn't
work.  Is there anything needed to get the broadcom 5703 going
besides ifconfig?

Well, I now have a root filesystem that works and one that
doesn't so I can slowly make one more like the other until
I see which piece is the culprit/magic.

Thanks,

Hi,

AFAIK, the TIGON3 driver in the latest 2_4_devel kernel does
not work with 5703. I did a code review of both the broadcom
and tigon3 driver and found that the open-source driver doesn't
have all the workarounds and, it doesn't support all the chips/board
flavors that are out there...

This brings up the bigger question of why people aren't using
the Broadcom OpenSource driver? I've used it successfully now
with all the latest chips (5700, 5701, 5703).

What does it take to add BSP and driver support to the 2_4_devel
tree?

			Thanks,
			-James

I guess so... I know it colloquially as a "Broadcom 5703 gigabit NIC"

Hmm, I got ahold of a 5701 and tried it.  Same behavior as my 5703.
I can load the driver, ifconfig it, the link status appears correct,
but can't transmit packets.

here's what I get (on the off chance that somebody will see this
and recognized the problem):

Upon loading the driver:

eth2: Tigon3 [partno(284685-001) rev 0105 PHY(5701)] (PCIX:133MHz:64-bit) 10/102

Then,
/sbin/ifconfig eth2 192.168.2.55 netmask 255.255.255.0 broadcast 192.168.2.255
eth2: Link is up at 10 Mbps, half duplex.
eth2: Flow control is off for TX and off for RX.

So far so good.

Then,
ping 192.168.2.55

Now, trouble:
(some debugging output is in here....)
sys_sendto
sock_sendmsg, sock=c3a8a1c0, len=64
scm_send returns 0
sk->prot->sendmsg = c00c1058
a b d g j L b e f g rt_intern_hash
A B C, n = -22z2, err=-22
rt_intern_has returns -22
err = -22
sock->ops->sendmsg = c00c9a50
sock->ops->sendmsg returns -22
err = -22
sendto: Invalid argument

so, it seems that in net/ipv4/arp.c, arp_bind_neighbour(),
__neigh_lookup_errno returns -22.

Don't know why.

Other NICs in the system (on-chip NICs) work fine.

Also, if I try to ping 192.168.2.0 (the network address)
ping doesn't bail, but I still get the -22 from arp_bind_neighbour,
and though ping claims such-and-such many packets transmitted, when
I do ifconfig eth2, I see:

eth2      Link encap:Ethernet  HWaddr 00:02:A5:E7:1C:Dand though ping claims such-and-such many packets transmitted, when
I do ifconfig eth2, I see:

eth2      Link encap:Ethernet  HWaddr 00:02:A5:E7:1C:D2
          inet addr:192.168.2.55  Bcast:192.168.2.255  Mask:255.255.255.0

          RX bytes:1448 (1.4 kb)  TX bytes:0 (0.0 b)

(notice, zero packets transmitted.)

Tigon3 driver, broadcom 5307, 440GP, working?

[Stephen Cameron]

I've been playing around with the tigon3 driver and a broadcom
5307 gigabit NIC in my IBM ebony... No luck so far.  The driver compiles
and even loads, I can run ifconfig(busybox really) to configure
the NIC,  and if I pull the network cable, the driver seems to
notice (get log messages about link is down, link is up) but so
far, I can't actually transmit or receive any packets.

Anyone had any luck with this combination?

I assume you mean a BCM5703?

FWIW, BCM5700/5701 on 440GP works for me with the current tg3 driver.
