NetBSD, Alix (i386) and network
Stefano Marinelli
Yesterday I had to get a new router (I need 802.11n) so I got a Cisco E3000. The router is ok, but now there's a problem with the Alix.
I can ping it, I can ssh into it, etc but ftp shows some "lags" when listing the files of a directory. When the transfer starts, it runs fast. More, Samba seems to be very very slow, especially when enumerating files on a directory or opening a file. It sits and waits. Then, when the transfer begins, it runs fine.
More, every night I do many rsync operations. They start in a proper way, then the upload speed falls down to less than 1 KB/sec (from my speed limit of 30, usually reached).
Putting back the old router completely solves the problem. I've performed some tests and it seems it just happens with the Alix. More, on the first ethernet port of the router, the Alix doesn't even respond to pings, even if the light shows it's "up and running at 100 Mbits". The only (big) difference between the old router (Linksys WRT54GL with dd-wrt) and the new one (with dd-wrt, tomato or the stock firmware) is the 1 Gbit ethernet capability. Is it possible that there are some problems between NetBSD, the Alix network chipset and the 1 Gbit integrated switch of the Cisco?
Here's my dmesg:

Any idea?

that does sound like auto-negotiate wierdness ... I don't know whether
it's related, however I have a Cisco for which my Asus 1000H ale0
doesn't come up properly and I have to manually set it to 10MB/s (!!)
before I get anything to work. My wife's netbook is the same model and
she has no problems with it at all - she is running Windows though, so
it may be a NetBSD driver issue ...
but try manually setting the link speed on your alix, then try
explicitly setting something on the Cisco and see if that helps ...

Actually, it might me as you say. Look at my ifconfig:
vr0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
address: 00:0d:b9:1e:4a:c4
media: Ethernet none (none)
inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255
inet6 fe80::20d:b9ff:fe1e:4ac4%vr0 prefixlen 64 scopeid 0x1
"media: Ethernet none (none)" ?
I will try to force other values. Let's see.

Solved. I had forgotten (months ago) to compile the ukphy support. With a 100Mbit switch I had no problems but it seems that with a faster one, it was confused.
Now it seems to be ok.
Thank you for pointing me in the right direction.

That usually means there is no cable connected.
What PHY does NetBSD detect for this interface? Please look for lines
like this in "dmesg":
brgphy0 at bge0 phy 1: BCM5750 1000BASE-T media interface, rev. 0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto
It will of course mention "vr0" in your case.
Kind regards

Thank you. As I posted some minutes ago, I didn't compile the phy support. It was working without problems when connected to a 100Mbit switch, but got "confused" with the new router, even if the Alix has a 100Mbit interface.
Anyway, after compiling the phy support, everything is working perfectly.

You said you compiled in ukphy(4) now. But ukphy(4) is only the last resort.
I would try a GENERIC to check whether there is a better PHY driver for
your hardware.
Kind regards

Yes, I've compiled ukphy(4) because the GENERIC kernel says it's the one it can use. So I don't think there's a more specific one for my hardware (Via Rhine III)

I don't know what's up with Cisco lately, but apparently they've decided it's
an OK idea to dilute their own brand by slapping the Cisco-name on products
that are barely worthy of being called Linksys.
I have an Cisco EPC3925 cable modem with built-in router and 4-point switch,
and from the looks of it there is some shared platform hiding underneath.
I recognise your problems, along with a few others (like ipv6 neighbourhood
discovery being broken). The EPC3925 has a known issue with autonegotiation,
if a device negotiates at 100 mbit that port becomes unreliable. Since I
can't easily replace the cable modem, I ended up installing a second switch
behind the Cisco modem. This fixed some (but not all!) of my problems with
this router.

Yes, ukphy(4) was the best I found to use when I was experimenting with
the same PC Engines ALIX board.
FYI to anyone else looking at this, the PHY in my tests identified as:
OUI 0x0002c6, model 0x0034, erv. 3
