Hi, It just occurred to me that /sys/class/net/*/wireless/ completely depends on wireless extensions. Since we're attempting to kill wireless extensions and hopefully will succeed in doing that some time soon, it is possible that people will be running with mac80211 drivers w/o CONFIG_WIRELESS_EXT. This leaves us in a sticky situation. People with CONFIG_WIRELESS_EXT will have /sys/class/net/*/wireless/ directories, but people without won't, and CONFIG_WIRELESS_EXT will not be necessary for a lot of people. Thus, I think we'll need to offer a /sys/class/net/*/wireless/ directory for cfg80211-only systems as well, since that'd also be the only way to tell if a device is wireless from sysfs. However, I'd much rather have that dir called ieee80211 in accordance with what we're doing elsewhere. But pre-802.11 equipment also uses wireless ext. Hmm :) We could create ieee80211 and create a symlink to it. Another thing we could do is simply deprecate the wireless directory there, but then wireless-ext users wouldn't have a way to tell if a netdev is wireless from sysfs.... Kinda feels like a "caught between a rock and a hard place" type of situation to me right now but I'm sure someone can come up with something perfect :P johannes
