[Click] polling! icr0xN

[Riccardo]

Hi,
	I'm testing the Click polling extension with a standard compliant 
router configuration.
My router as 3 GigaEthernet interfaces: two e1000 adapters (eth0, eth1),
for which I use PollDevice, and a Netgear GA302T (eth2). This one is
obviously not pollable, so I've to use FromDevice.
During some tests appears this mex:

"eth1: polling! icr0xN" (N = 1, 2 or 3)

I found out it in the source code (function "e1000_intr", file
"e1000_main.c"), but I didn't understand what kind of problem is.
Where can I find more info?

Thanks,
Riccardo.
