Some help about backporting a nic module to 2.6.32 longterm

From: André Ferraz <hidden>

Hi Greg,
	the problem is that i need to stay with the 2.6.32 grsec
	patchset for my servers, if i didn't have any dependencies like
	that sure i'll be using the 3.2 kernel.

	The idea is to just backport this device driver, the rest of
	the drivers works pretty well, but i didnt find any HowTo or
	some documentation specific to the process of update a driver
	on your kernel source.

Hi,

	I'm using the 2.6.32.x longterm series for our servers but
we are facing a problem with the bnx2x driver module in our latest
	G7 HP blade servers, the module exists but it doenst ping
and cant access any node in the network, i saw too that the
	broadcom and hp driver specs can't build on 2.6.32 kernel
	because they only support the 2.6.18 redhat series. The
version maintained by CentOS/Redhat om 5.x release works but it is
	based on 2.6.18 kernel.

	My initial idea was pull the CentOS 6 kernel source (based
on 2.6.32) and make a patch of the bnx2x driver for my kernel
	source, the patch applies but when i boot the kernel the
	version it remains the same, i saw that the /firmware
directory has some bnx2x files on it, my question to you is that i
	couldnt find anywhere is how the .c file and the .fw
	correlates , or , how can i create a real backport of this
	driver so i can use an usable version of the driver for the
	longterm release?
Why not just use the 3.2 kernel release, where this should be fixed
already, right?

Once you start backporting "bits and pieces", you can quickly end up
with an unmaintainable mess, not to mention something that no one,
including the community, or any company, will ever support.
