Why is iwlwifi still at version 1.2.23?
Is there some problem with it?

I assume you are referring to the out of tree driver available from
intellinuxwireless.org. 

iwlwifi has been included in the kernel since 2.6.24, for this reason
development has shifted to focus on upstream. The repository at
intellinuxwireless.org has not been receiving changes since release of
1.2.23 - all changes go directly upstream. You can use the latest
upstream driver by utilizing the compat-wireless project
(http://linuxwireless.org/en/users/Download). Currently the upstream
driver also has version number 1.2.23 - even tough it received
significant changes since the out of tree release of 1.2.23. To reduce
this confusion we did send a version update to the development tree
(making the in kernel iwlwifi be version 1.2.26), this change is still
to be applied.

Version numbering does make less sense now that we are in the kernel ...
please be assured that you are using the latest driver when you are
using the compat-wireless project.

Someone please expediently fix whatever it is that makes the iwlwifi
drivers rebuild every single time I type make.

It's a real intense pain when I have an 'allmodconfig' tree for build
validations, I pull some unrelated changed into the tree, and I see
iwlwifi rebuild no matter what.

This is not sane behavior.

Thanks.

I'm trying allmodconfig on wireless-testing now. It takes some time to
finish make. But a simple running "make M=drivers/net/wireless/" twice
doesn't show this issue.

It's the include of generated/utsrelease.h by iwl-core.h that causes
the rebuild.

Thanks. It was first introduced by below commit. And was later changed
to use generated/utsrelease.h. I'm wondering if we should really use
linux/utsrelease.h (or linux/version.h) or remove the kernel version
totally from the driver version (driver compile tag can be remained).
Any suggestions?

Thanks,

    iwlwifi: driver version track kernel version
    
    The driver version number is a remnant from when there was an out-of-tree
    iwlwifi driver. Now that the driver forms part of kernel source we do not
    need a separate driver version. Instead, we now use the kernel version as
    driver version. We maintain the previous tags used to indicate which
    components the driver has been compiled with.

Remove the dependency, every time you type make the build number
increases and this will force your driver to rebuild.
