This is a RFC for inclusion of the Intel igb wired ethernet driver.
Patches are split per kernel release that makes it easier to review
the changes and gives a nice history of what was necessary for each
release. Also the igb driver changes have been split up into individual
patches in patches/collateral-evolutions/network/82-ethernet. This and
file names are up for discussion, suggestions welcome.
Support goes back to kernel 3.0 since current igb relies on ptp support
which got introduced in 3.0. Currently the patches still break for
kernel before 3.0 but I wanted to get the RFC out, this should be fixed
next time.
One thing I'm not sure how to fix is the following HWMON warning.
make KLIB=/lib/modules/3.0.0 defconfig-igb
make[2]: `conf' is up to date.
boolean symbol HWMON tested for 'm'? test forced to 'n'
boolean symbol HWMON tested for 'm'? test forced to 'n'
Patches apply against tag backports-20131206, feedback is very welcome.

- add pci_sriov_set_totalvfs()
- add patches/collateral-evolutions/network/82-ethernet/igb_pci_sriov_configure.patch
Thought of backporting struct pci_driver like this:
struct backport_pci_driver {
[...]
};
but that introduces the following.
CC [M] /dev/shm/next/drivers/net/ethernet/intel/igb/igb_main.o
/dev/shm/next/drivers/net/ethernet/intel/igb/igb_main.c: In function ‘igb_init_module’:
/dev/shm/next/drivers/net/ethernet/intel/igb/igb_main.c:698: warning: passing argument 1 of ‘__pci_register_driver’ from incompatible pointer type
include/linux/pci.h:1002: note: expected ‘struct pci_driver *’ but argument is of type ‘struct backport_pci_driver *’
/dev/shm/next/drivers/net/ethernet/intel/igb/igb_main.c: In function ‘igb_exit_module’:

include/linux/pci.h:1011: note: expected ‘struct pci_driver *’ but argument is of type ‘struct backport_pci_driver *’
Adding these as well would drag along several pci dependencies and I'm not sure
this is really safe. Opinions?
For now I've just commented out the code.

PCI should not be selected here, because it has to be selected in the
kernel you are compiling against. I have not analyzed this, but I thing
the defconfig should just contain these two options, the others should
be already activated in the kernel:
CPTCFG_NET_VENDOR_INTEL=y
CPTCFG_IGB=m

This should be added in the last patch otherwise backports will not
compile between this patch and the last one, becaise some parts are missing.

Backporting ethtool_ops does not work so easily. The network stack is in
the old kernel which want to call some function with a pointer from this
strcut, but it accesses this option not by its name but by the offset in
this struct it was compiled with. If the kernel and backports are
getting compiled with a different version of this struct then they could
have a different opinion on where a certain function pointer is placed
which will lead to the kernel calling the wrong function. You have to be
careful when you want to change some structs in backports, this normally
only works when all users of this strut are in backports.

I'll see if I can boil this down. I had some trouble with older kernel
to get igb recognized.

Right, this was only a RFC and to see what breaks I had to enable it

I agree with you there, so what would be a better way to deal with
changes in struct ethtool_ops? We probably could ifdef out the code in
igb but I assume that would get very ugly rather quickly and would take a
lot of time to maintain and refresh patches against upstream. A solution
which keeps the changes to upstream minimal would be preferable if you
could think of any.
