Hello,

I often post with updated e1000.  Has the i82544 also been kept uptodate, I'm looking for the irq_threshold featurs. 
Also I read somewhere that i82544 can perform better under heavy load ( less interrupt for the same amount of network 
traffic? )

Re: i82544

No, the i82544 driver hasn't been updated, only the e1000.

Thanks for the info. Is it true that this driver can reduce CPU (interrupt) overhead compare to the e1000?

Re: i82544

The latest e1000 driver has a new command line option to allow you to
change the interrupt moderation value, so you can inform the driver to
interrupt more or less for received packets.
