Interesting, I get 11.6MB/s peaks with multiple 100mbits.
3COM's have been great here.
I have 4-5 100mbit 3COM NICS (905bs) (PCI).
And about 10-20 10mbits (ISA+PCI).
All have worked great!
Usually when people have problems with 10/100mbit, they have a half duplex hub or
something lol.

As far as speed is concerned:
Half Duplex hub = Worst
Full Duplex hub = Better
100mbit full duplex switch = best

Well, most of those have just one packet sized buffer, so they are hubs
performancewise, while they're switches by technology ...

Based on my reading of 3c59x.c, 3c905B and 3c905C cards - but not the
original 3c905 - will do TCP checksums in hardware (and thus enable
zero-copy data transfer).

Recommendations about a 100/10 NIC

[janvapan]

What ethernet cards I should use for Linux 2.4?.
I am looking for a NIC based on stability and performance.
In short, Intel PRO/100 S Desktop Adapter(e100 driver) or
3Com 10/100 3C905C-TX-M(3c59x driver) ?

thank you,

Re: Recommendations about a 100/10 NIC

[Justin Piszcz]

I'd reccomend a 3COM, as they come with a lifetime warranty and have always
been good for me.
Not sure about Intels.
I have a 3com 905b, the current model is a 3com 905C-TX like you mentioned.

Does lifetime warranty mean you have warranty on them as long as they are
alife?

All of them do ethernet checksums^W CRCs in hardware.

Did you mean something like, "which ones do IP and/or TCP
checksums (offloads) in hardware?"

Re: Recommendations about a 100/10 NIC

In my humble experience with some hundreds
of different Linux servers, the 3c905 seems the
most trouble-free, and performs well.

The Intel adapter has potential driver issues,
although they seem to be getting resolved.

The e100 driver has the disadvantage of being
unable to work with the mii-tool commands,
but seems to work well otherwise - as long as
you don't mind trying to puzzle out whether
the card is conected at 10 or 100, full or half.

The eepro100 driver works with mii-tool, but
many have reported issues with the card dying
under heavy use and needing to be reset. Many
are using the eepro100 without problems - but
the bottom line is that nobody is seeing these
problems with the 3com cards.

YMMV of course -

Hmm, the only multiport cards I've used are
some tlans and some intel pro 100s -

The tlans are no good for serious use, at least
in my experience - I've been replacing them
as replacements are available.

The dual intel 10/100s I've used work fine,
they are simply detected as 2 intel ethernet
devices.

Linda, I've got a dual port Intel eepro100 card in this machine. I've had 
it close to a year, with nothing but excellent performance and stability. 
I can't say the same thing for other cards i've tried in here, namingly 
the 3com adapters everyone seems to think are so great. I won't even touch 
a 3com adapter anymore, but i digress...  These dual eepro100 cards can be 
had used for relatively cheap; i think I purchased this one for $45USD 
when i bought it...

Haven't had any issues at all with eepro100 or e100 under production
load for years.  Since Tulip went out of the mainstream (poor Digital)
the EtherExpress has been the most stable everywhere I've been.  I've
written too many scripts for 3Com boxes that grep dmesg for "fatal"
errors and unload/reload the 3com module.

That's all logged (dmesg, etc), if not distinctly queryable.  Don't the
iANS tools allow this functionality, and more?

Uhm, "nobody" is certainly not the proper word in this context.  We've
pulled many 3Com cards because of issues, including ARP deafness,
overruns, hangs, etc.  I have fully-saturated IDS systems running
eepro100 and e100 without issue, so heavy use may be necessary but is
not sufficient.

Oh, and six years of production on hundreds of EtherExpress NICs with
zero (0) issues.  Obviously, not everyone sees every bug, but the
preponderance of evidence I've seen in production environments puts the
EE way ahead of 3Com.  3Com for Windows desktops works just fine.

I'd like to try existing Tulip hardware though for another option.
Though 8139too seems to work well.

Ran into problems with Intel EtherExpress cards under Alpha a while back,
and I've had a _lot_ of problems with the revision of the EtherExpress
built into motherboards, versus the intel or kernel drivers for them.

My stock recommendation is thus SMC EtherPower II cards.

Have you tried those with cables longer than 20 feet?  I was totally happy
with my Netgear cards with a 10ft crossover until I tried connecting a
couple of new computers to my file server in the closet with 25ft CAT5
and then all the UDP (most noticeably NFS) traffic turned to crap.

I returned everything and got all D-link hardware.  Works great.  I'm not
going to buy Netgear hardware for the foreseeable future.

I've had luck with them too, as well as the SMC EZNET cards (8139too
driver) in workstations, windoze boxes and freebsd.

But the EZNET NICS especially seem to crack up under high load.

Not all revisions behave the same here. For a few months, I've seen
3c905{b/c} working fine where etherpower II suffered.

The SMC cards used to be Tulip before epic.  I had the same module
problems with epic too, so we had to go to EE from Tulip when that
happened. :(

I suspect a lot of the problems depend on the motherboard or
architecture, as well as the switching hardware.

yes, you can grope through the logs (as part of
the process of puzzling it out) and there are
ways to get the information - but it's so much
nicer to just get the speed and duplex from
an mii-command, on the spot.

Well, like I say it's a mixed bag. We have mail/dns
servers (580 dns domains, 100,000 messages/day)
that have been runing for over 600 days, and not
a hint of trouble from the eepro100 drivers.

OTOH we have some new dell boxes with intel
pro 100 nics where we can quickly get the "eth0
reports no resources" message and poor or no
connectivity with a couple hours of apachebench
on a 100 MB lan.

could be a chipset issue...
