Hi again,
Finally, my hardware supplier in California has been VERY nice, and has
made it possible for me to have access to a server equipped with the
Supermicro X8STi-F motherboard that we want to use later on in
production. As the guy is really awesome, I want to name him publicly.
If you need any kind of hardware for servers, ask to talk to John Wu at
KingstarUSA in California. He will reply to you within minutes, and make
reasonable quotes. He will also be able to support you with any issue
(like now). Drop him a mail if you need, his is as Cc: here. Give him
some business, he deserves it!
Anyway, back to the patch. I have tried to apply all the patches that
Ben sent to me, and this is NOT ENOUGH to have the e1000e working. In
fact, we have to realize that, if it's still the same Ethernet
controller name (I mean e1000e), it's quite a different controller. The
one on that motherboard is a 82574L, which seems to be a more recent
model. The driver source in the kernel has many specificities for it. So
if you guys, at the kernel team, decide to add and maintain a patch,
this will NOT be a tiny one just adding new PCI IDs...
Please read (quickly) the diff file that I have attached, it shows
better than anything else what I'm talking about. It was done the
"wrong" way: taking the sources from 2.6.29 (from backports.org), making
a diff -r -u of the e1000e folder, and apply corrections until it
compiles, including some kernel API changes that I had to backport. It's
a bit ugly, but IT DOES work very well, and I'm quite happy that I have
at least the solution to apply this patch to the Debian kernel sources.
Now, if you still think that there is a possibility to have a patch
included (which would be, to my eyes, a very wise decision), I guess
that I'd need to apply patches from Git again in order to make it
cleaner and smaller. I have searched, and couldn't find the gitweb for
the e1000e project.
Ben Hutchings, would you be able to do what you did before: give me a
patch collection that I can apply one by one, until I can see the driver
working? This time I need MORE patches, at least until kernel 2.6.28 (as
the driver appeared to work with the backported Debian CD including
2.6.28 kernel). Then I'll do my best to make a much smaller patch than
the one that I have attached, and hopefully, have it accepted by you guys.
Thanks for your time reading this, and the support of my work here,
Thomas
