Dear list,

I hope I am posting to the correct place...

I am facing a strange issue on a HP DL 360.

I have 2 internal ethernet cards (the one that came by default with
the server) and 2 additional ethernet cards for a total for 4 ethernet
cards.

The 2 internal cards are running fine as of interrupts (for example eth1):
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
      CPU6       CPU7

  71:        604      11933         40       1537          0

  73:          0        279          0        429         38

46      63064         18   PCI-MSI-edge      eth1-6

82       7846      27130   PCI-MSI-edge      eth1-7

On eth2 (external card) all interrupts goes to CPU0
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
      CPU6       CPU7

0          0          0   PCI-MSI-edge      eth2-7

If I understand correctly the RSS hash is used to dispatch the packets
into the different queues running on the different CPU.

Why then my internal cards are running fine but the additional cards
(eth2 and eth3) are presenting this behavior where all interrupts goes
to one CPU?

Thanks for your help in understanding this. (see below for config details)

Christophe.

It looks like most interrupts go to eth2-0, a few go to eth2-6.  The rx
ring for eth2-0 is for non-IP packets.  The RSS hash will hash IP
packets and place them on eth2-1 to eth2-7.  eth2-0 also handles tx
interrupts for TX ring 0.  TX traffic is hashed by the stack.

What kind of traffic is passing through eth2?

Thanks.

Hi

Well that's the strange thing: it is IP traffic. The only difference
with eth0 and eth1 is that eth2 and eth3 belongs to a bridge (br0).

Best Regards,
Christophe.

Is it a requirement that the interface has an IP address for the TX
and RX hash to work?

Christophe.

At the risk of typing into Michael's keyboard, chances are, what the NIC does is 
follow Microsoft's specs for RSS, which as far as I can tell, discusses hashing 
either just on the IP addresses (v4 or v6) or the IP addresses and TCP port 
numbers, so unless Broadcom has an enhancement/extension, if the traffic 
arriving is not TCP/IP and not multiple connections, it probably does not get 
spread-out.

Traffic is IP no doubt about that. Lots of TCP and UDP traffic. I can
provide a very short pcap if you want (lots of traffic so pcap can be
big really quickly).

- The 2 interfaces that have this problems are running in promiscuous
mode (without having an assiged IP address to the interface) inside a
linux bridge interface (br0), but the traffic that is bridged is IP.

- The other 2 that works correctly: are not in promiscuous and have an
IP assigned to the network card.

So I am thinking that for some reason the RSS is activating only when
a specific configuration is set on the interface but not just on if it
is IP traffic or not.

Best Regards,
Christophe.

Dear list,

So i've been able to do some test today:
If I put the 2 interface in a bridge with no IP adress, the interrupts
are on 1 CPU
If I put the 2 interface in a bridge with IP adress, the interrupts
are still on 1 CPU
If I put the 2 interface outside the bridge with IP address,
everything works fine the interrupts get spread on the CPU

So the conclusion seems to be that when the bnx2 is put into
promiscuous mode by the bridge, the RSS hash stop to work even if
traffic is IP in nature.

Best regards,
Christophe.

I did a quick test with bridging and saw no problem with RSS.  I did see
this though:

br0 received packet on queue 4, but number of RX queues is 1

Looks like it is a warning message from RPS.

Christophe uses an old kernel, not RPS enabled ;)

Right, I'm reporting a related problem on a newer kernel with RPS
enabled.  And the fact that it is receiving packets on queue 4 shows
that RSS is working together with bridging.

I'll try to use an older kernel to see what happens later today.
