The developer of the famous aircrack has one good tool, aireplay that can be used to assess security of the wireless networks. This requires patching of the current driver. The patch is included in the http://www.cr0.net:8040/code/network/aircrack-2.3.tgz distribution. I would suggest adding an option in the ebuild that would allow for this patch to be automatically applied. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Please get this patch accepted by upstream, and it will automatically be available in Gentoo Portage when a new version is released.
