[tulip] interupt mitigation on a DFE-570TX - where's the secret sauce?

[Roisman, Dani]

Hello,

I have a D-Link DFE-570TX with four 21143-TD ports.

I'm using version 0.92t of the tulip driver, and it isn't performing as if
it's doing interrupt mitigation.  I'm comparing the pps that I'm sending it
to the interrupt/sec info that I get from vmstat or looking at
/proc/interrupts.

Browsing through tulip.c, this line leads me to believe that I should see a
message sent to syslog (I'm logging *.*) about interrupt mitigation when I
load the driver:
printk(KERN_NOTICE "%s: Set interrupt mitigate paramters %8.8x.\n",

I don't see any such line logged, only the standard:
eth1: Digital DS21143 Tulip rev 65 at 0x3000, 00:80:C8:CA:55:68, IRQ 20.
eth1:  EEPROM default media type Autosense.
eth1:  Index #0 - Media MII (#11) described by a 21142 MII PHY (3) block.
eth1:  MII transceiver #1 config 3100 status 7869 advertising 01e1.

I tried turning debug to level 7 in tulip.c and recompiling.  I got a lot of
noise in my syslog, but nothing about mitigation.

Is there something I'm missing???

Thanks.
