Hi,
I'm not sure if I'm much help, I have the same chipset, VIA Rhine II on
a 6.1-p10 and works fine on a production server
# pciconf -lv
[EMAIL PROTECTED]:18:0: class=0x020000 card=0x1421147b chip=0x30651106 rev=0x78
hdr=0x00
vendor = 'VIA Technologies Inc'
device = 'VT6102 Rhine II PCI Fast Ethernet Controller'
class = network
subclass = ethernet
The ping -s 1500 other.host works with no packet loss.
You chip id looks the same, but the revision looks slightly newer.
Cheers
David

I also did a little more digging and noticed that once I start
pinging from one of these hosts using large packet sizes, I get
about 50-60% packet loss (ie: ping -s 1500 other.vr0.host). If I
ping something with a decent card, I get about 30-50% packet loss.
There's no packet loss with the default packet size.
Anyone else with some vr cards feel like checking this out?
I've got a VIA Rhine III card that I can dig out and put in if the
data would be of any use/interest etc - FWIW I seem to recall being
able to get reasonably close to wire speed when I was using it.
I plugged in the card today, and seem to get pretty reasonable
performance (8-10MB/s for scp - see attached). The two boxes are
plugged into a Linksys router via store made cat5 or cat6 cables. The
second box has an Intel PRO 100 (fxp) adapter.
Interesting. I've had the vr hosts going through three different
switches, patch cables, the in-house cabling, and the issue remains
the same. I'd love to just replace a cable and be done with it, but
that doesn't seem to be the issue. I can also eliminate it by just
switching out cards... so I don't really suspect I've got a whole
load of bad cables.
Removing the vr card and going back to fxp everywhere seems to
provide better performance (e.g. get 9MB/s in the last test), but the
vr performance is acceptable (maybe your router clashes with your
card?).
Mine borders on unusable. The packet loss really slows down and
stalls TCP connections.
I noticed you have a newer revision of the Via card:
# pciconf -lv

This is what I'm dealing with:
[EMAIL PROTECTED]:17:7: class=0x060000 card=0x287e1106 chip=0x287e1106
rev=0x00 hdr=0x00
vendor = 'VIA Technologies Inc'
class = bridge
subclass = HOST-PCI
[EMAIL PROTECTED]:18:0: class=0x020000 card=0x80a71043 chip=0x30651106
rev=0x7c hdr=0x00 vendor = 'VIA Technologies Inc'
device = 'VT6102 Rhine II PCI Fast Ethernet Controller'
class = network
subclass = ethernet
Maybe I'll just round up as much info as I can at my next visit, grab
some tcpdumps of the loss from both ends and do a send-pr and hope for
the best. I can get along with replacing the cards, but they seem to
be really common these days - basically any cheap system with a Via
chipset and onboard ethernet will be using some variation on this
controller.
