free tg3 ethernet driver

free tg3 ethernet driver

[Davi Leal]

We would like to have a tg3 driver which would be accepted as free by the 
FSF's standards.

At least some part of the driver seems to be GPL'ed; see [1].  However, the 
FSF's hardware guide lists tg3 as non-free, so there seems to be a non-free 
firmware somewhere.

We would like to be able to use the free driver with Linux 2.6.27 or later.

Well if you want to write new firmware for the device you'll need to
reverse engineer the chip internals or convince Broadcom to document them
for you. I suspect you'll have to get to the point of xraying the
component slice by slice and need a multi-million dollar budget.

I would like a pony.

Firmware blobs aren't news.  They've been discussed at great length on 
this list.  If you want to whine about this, whine to Broadcom.

You must be new here.

Gigabit NICs with firmware-free drivers cost $10.  If you care that much 
about the binary blob in tg3, maybe you should stop giving your money to 
Broadcom, and start giving it to vendors whose drivers satisfy your 
requirements.

People position seem to be continue to pledge to pay $151 to the developer(s) 
(even if it's Broadcom in case they apply to the pledge system) who provide a 
free driver for tg3 devices.

Well thats good, another 1.999849 million dollars and you might get
started.

With the best will in the world if you go and pay Broadcom zillions to
open source the firmware the only incentive you create is for them to
keep future firmware proprietary to sell to you next time around.

If on the other hand you buy non Broadcom equipment if you feel this
way about the firmware then you create a far better economic incentive,
and at $10 a NIC its not really hard to do that.

Very true. If I start cooking awful cakes and I see people come to pay
me for throwing them away, I'll sure restart ASAP.

And that's not counting with the fact that their crappy BNX2 has been
showing horrible performance for several years now on servers, dropping
frames like mad, and reminding the poor reliability and performance of
Dlink's DL2000...

We have added your new comments in the pledge description.
