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.
