Re: [Xen-users] XEN - Broadcom issue: survey



Sorry to make the counter-example but I have:

~# ethtool -i peth0
driver: bnx2
version: 1.4.51b
firmware-version: 2.9.1
bus-info: 0000:04:00.0

this driver is the one relased by DELL on Nov. 11, and I have packet drop. The same with driver 1.5.1c from broadcom

The strange thing is that TX-DRP is 0 until I start a domain. Since I start an HVM, TX-DRP for its vif start incresing.

If I start an PV machine, it drop only 20 packets and then stop. No more TX-DRP at all...

So, to isolate the problem, it is related to HVM machine only. At least in my case.

Hey,

please note that if you're using the tg3 driver, it means you're using
NetXTreme *not* NetXTreme II (the latter is using the 5708/5706 chipsets,
the former some previous releases). The problem has been observed (but I'd like some confirmations here ;-))
using the bnx2 driver, which is specific to NetEXtreme II.

To make sure what driver/version/firmware you're using you can run 'ethtool
-i eth0' (replace eth0 with the ethernet device you want to show).

In my case, the "bad" machine shows:

[root@sofia ~]# ethtool -i peth0
driver: bnx2
version: 1.5.10c
firmware-version: 1.9.3
bus-info: 0000:03:00.0

while the "good" machine shows:
[root@camogli scripts]# ethtool -i eth0
driver: bnx2
version: 1.5.1c
firmware-version: 2.9.1
bus-info: 0000:08:00.0

As I said before, the only relevant difference I can find between the 2
machines is the eth0 firmware version, but I don't now if and how I can
update it on the other one (ref to my previous message for the complete
details on the good and bad machine configuration).

I totally agree with Luc Boudreau about this problem.

On modern branded server they ALL use Broadcom chipset... I must admit that:

a) lot of people are experiencing the problem but can tolerate it

or

b) someone already experienced this problem and solved it
Too bad you started a new topic without even trying to describe what your problem with broadcom chipsets is?

I'm running Xen 3.1 (2.6.18 kernel), compiled from sources, on HP ProLiant DL320 G3. It uses tg3 for its network cards.

Works fine.
