Now it's too late, those changes have propagated to userspace
tools, and are now shipping in some actual release of some distro. So,
what are we going to say to Mandriva 2007 and FC6 users, to revert
back to an *older* version of the tools ?
Because userspace has already been updated, we have only two
options, merge it now, or in 2.6.20.
If the choice is between the ABI used by a bunch of distros in
production, and the ABI used by two re-release distros, I think the
choice is obvious...
I (grudgingly?) agree...
Unfortunately, I don't see any way to "fix" WE-21 without similarly
breaking wireless-tools 29 and other "WE-21 aware" apps. And since
I'll bet that the various WE-aware apps have checks like "if WE >
20" for managing ESSID length settings, we may have painted ourselves
into a korner (sic).
I.E. With "WE-21 aware" tools already in the wild, it isn't now clear
to me how WE can evolve any further than WE-20. Unless the ESSID
length changes in WE-21 is somehow deemed acceptable for 2.6.20 or
some later kernel version, I don't see how WE can continue to change.
Wireless developers, it's time to get d80211 ready to merge...or
figure-out how to get nl80211 on the current stack...hmmm...

- *
- * The issue : wireless_send_event() is often called in interrupt context,

- * The fully formed RtNetlink events are queued, and then a tasklet is run
- * to feed those to Netlink.
- * The skb_queue is interrupt safe, and its lock is not held while calling
- * Netlink, so there is no possibility of dealock.
