[2.6.6] eepro100 vs e100?

Hello List,

I'm currently in the process of cleaning up my 2.6 kernel configuration on my 
trusty SMP HP Netserver LC3, which comes shipped with 2 identical intel Pro 
Ethernet 100 mbit cards:

0000:00:08.0 Ethernet controller: Intel Corp. 82557/8/9 [Ethernet Pro 100] 
(rev 05)
        Subsystem: Hewlett-Packard Company NetServer 10/100TX
        Flags: bus master, medium devsel, latency 66, IRQ 16
        Memory at fecfd000 (32-bit, prefetchable)
        I/O ports at fcc0 [size=32]
        Memory at fed00000 (32-bit, non-prefetchable) [size=1M]
        Capabilities: [dc] Power Management version 1

I'm wondering what driver is the "best" one to use? Judging by the comments in 
the files, the e100 driver seems to be the best maintained, though I'm 
probably wrong ;p

The website that is referenced in the eepro100 driver is no longer available 
(returns a 404).

If someone can shed some light on this, thanks!

Jan

We have a usenet server we use with 2.6.6 kernel and the eepro100 gives
IRQ problems:

Where as the e100 is rocksolid (knock wood) under sometimes heavy load:

So _i_ would advise the e100 driver.

I would suggest e100 from practice. The onboard Ethernet of Intel
D815EEA2 mainboard works fine in 100Mb/FD with both drivers but started
acting strangely in 10Mb/HD network with eepro100 (e100 seems to be OK).

I've always had good results with the e100 driver:

Intel(R) PRO/100 Network Driver - version 2.3.36-k1
Copyright (c) 2003 Intel Corporation

e100: selftest OK.
e100: eth1: Intel(R) PRO/100 Network Connection
  Hardware receive checksums enabled
  cpu cycle saver enabled

While initially there did seem to be lockups with multiple e100 devices, 
I haven't seen that in some versions. I have several servers which run 
the NICs at 70-80 Mbit all the time and see no issues with the e100 at 
this time.

There seems to be some maintenance going on there see:
