[Click] Polling patch problems with Intel 82571EB.

[Egi, Norbert]

Hi Matt,
 
Thank you very much for the patch, I've been testing it quite a lot and can say that it is very stable, although I have some performance issues with it. With one interface I'm polling the maximum possible rate (1.488.095 pps) out of the interface, but when I have two interfaces up the rates go down to around 1.000.000pps with multi-threading. It stays on this rate for all time, but I know that with the (in my system unstable) patch of the CVS I was able to pull max rate from both interfaces, only of course when it happened to work.
 
Can you tell me what packet rates you get out of two interfaces, if you have measured it yet?
 
I also tried removing the reset code and the mod_timer lines, but in those cases it didn't really work in my system either.
 
Cheers,
Norbert

Hi,

I am able to poll two 82571EB pci-e interfaces in the same click config
on Intel SR1500 servers without problems.  I am using this attached
driver patch which is slightly different than the one in CVS.

You should also try to remove the reset code in e1000_poll_on (and
modtimer lines in this patch).  That does not work for me in this setup
though.
