"I'm trying to keep some external drivers up to date with the kernel, and the first two weeks after the release is the worst time for me. There is no way to distinguish the current git kernel from the latest release. It's only after rc1 is released that I can use the preprocessor to check LINUX_VERSION_CODE," explained Pavel Roskin, describing the ongoing effort to keep the out of tree MadWifi driver in sync with the latest released kernel. Rik Van Riel suggested:

"Consider this an incentive to submit your code for inclusion in the upstream kernel. Having all the common drivers integrated in the mainline kernel makes it much easier for users to use all their hardware, external drivers are not just a pain for the developers."

Pavel acknowledged, "the incentive has already worked for MadWifi, which has landed in the wireless-2.6 repository under the name 'ath5k'. Still, there is a lot of work to do, and some features won't appear in the kernel driver soon, partly because they rely on the chipset features that still need to be reverse engineered. " In response to Pavel's original question, Dave Jones noted that Fedora kernels treat the development between a major release and the first release candidate as "rc0".

James Ketrenos announced a new 80211 based driver for the Intel PRO/Wireless 3945ABG network connection adapter, "this new driver uses the new d80211 subsystem previously only available as part of the wireless-dev tree." An earlier incarnation of the driver code was much criticized for its inclusion of a userland binary-only daemon [story], prompting the OpenBSD project to create their own blob-free driver for the card [story]. "The [new] iwlwifi driver for the 3945 does not require the user space daemon, but does require a new microcode image," James explained, "over the past year we were able to make the necessary changes to the microcode used with the 3945 such that we were able to remove the regulatory daemon."

When the question was asked if the driver was going to be pushed for inclusion into the mainline kernel it was noted, "hmmm...I think we need to spend a cycle or so in -mm. 2.6.22 seems more likely for mainline." Pavel Roskin suggested, "iwlwifi is surprisingly good for a just announced driver. It worked for me from the first attempt, and that's the first d80211 driver to do so. In my opinion, it should go to wireless-dev as soon as possible so it can go to -mm together with other drivers."
