2.6.29-rc "TKIP: replay detected" regression

[Hugh Dickins]

Prior to 2.6.29-rc1's 274bfb8dc5ffa16cb073801bebe76ab7f4e2e73d
"lib80211: absorb crypto bits from net/ieee80211", the TKIP and CCMP
"replay detected" messages were subject to the IEEE80211_DEBUG_DROP()
macro, neither I nor my distro had CONFIG_IEEE80211_DEBUG set, I never
glimpsed such messages, and ThinkPad T43p ipw2200 wireless worked fine.

-		if (ieee80211_ratelimit_debug(IEEE80211_DL_DROP)) {
-			IEEE80211_DEBUG_DROP("TKIP: replay detected: STA=%pM"
+		if (net_ratelimit()) {
+			printk(KERN_DEBUG "TKIP: replay detected: STA=%pM"

Wireless is still working fine - thank you - but now that such messages
are not CONFIG'ed out, my /var/log/messages is getting cluttered with
"TKIP: replay detected"s, and more unpleasantly (because I have WARNINGs
to screen) occasional "__ratelimit: NN callbacks suppressed" appearing.

Messages from the last day appended below: only one CCMP, but two
kinds of TKIP message - sometimes it's just the same TSC repeated,
but more irritating are the sequences when it gets a reset to zero
"previous TSC 000000000dbb received TSC 000000000000" followed by
message (or suppression) as it goes on to receive 1, 2, 3, ...
The AP here, if it's of any interest, is a Siemens Gigaset SE587.

I've not correlated these bursts with any bad behaviour at all,
reception seems fine even amidst these sequences: so I'd be glad
just to have those messages suppressed again - and of course can
patch them out of my own kernel builds, but others may suffer too.
