Re: [PATCH 1/2] igb_uio: fix compability on old kernel

quoted

This is what we came up with. It works for us. In our kernel headers'
linux/pci.h, pci_num_vf is enclosed within "#ifdef
CONFIG_PCI_IOV/#endif";
pci_intx_mask_supported and pci_check_and_mask_intx are enclosed within
"#ifdef HAVE_PCI_SET_MWI/#endif".

What do you think?

Maybe we can just get rid of kernel version checks all together and
just use the HAVE_ checks.

I will test on stock 2.6.32.

Sorry, I spoke too soon. Although it builds with the ifdefs, I just found
that it does not load.
