Rate control algorithms are supposed to stop processing when they

zero is not enough.

Allowing a rate with negative index leads to memory corruption in

mwifiex: clear previous security setting during association

Driver maintains different flags for WEP, WPA, WPA2 security modes.
Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is
aborted if the routine fails.

For some corner cases, it is observed that association is failed
even for valid security information based on association history.
This patch fixes the problem by clearing previous security setting

This missing change is also added here.

have the rfcomm_process_rx doing an explicit put and in the initiator
case the last dlc_unlink will drive the reference counter to 0.

683d949 Bluetooth: Never deallocate a session when some DLC points to it

mac80211: rename mesh static path_lookup()

If you want to use mesh support from mac80211 on a recent
kernel on 2.6.24 you'll run into a name clash when compiling
against include/linux/namei.h, so rename this routine.

/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c: At top level:
/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c:342:26: error: conflicting types for ‘path_lookup’
include/linux/namei.h:71:12: note: previous declaration of ‘path_lookup’ was here

Although this could sit as a separate patch in compat-wireless it seems
best to just merge upstream.

zd1211rw: firmware needs duration_id set to zero for non-pspoll frames

Some devices (iwl5100) cannot connect to zd1211rw based AP. It appears that
zd1211 firmware messes up duration_id field if it is not set to zero by driver.

Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits
14 and 15 set and other bits appearing random. Setting duration_id at driver to
zero results zd1211 outputting sane duration_id. This means that firmware is
setting correct values itself and expects duration_id to be zero in first
place.

Looking at vendor driver shows that only PSPoll frames have duration_id set by
driver, for other frames duration_id left zero.
