It didn't exist in v2.6.22. You can see this with the command: $ git log -- drivers/net/wireless/bcm43xx-mac80211 Where the last listed commit is d05daff. So of course there will be many bisection points back to v2.6.22 where that directory just doesn't exist. A bit of digging with Git shows this history for most of the files in that directory: renamed in v2.6.23-rc1-1621 as bcm43xx-mac80211 renamed in v2.6.21-rc1-809 as mac80211 renamed in v2.6.17-rc2-357 as d80211/bcm43xx Imported in v2.6.16-1725 as bcm43xx-d80211 HTH, Sean - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
