Wakeup interrupt has been updating write pointers (indexes, actually) only

so device can be aware of all new tx and host commands enqueued while

iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000 series
When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection
mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field
in the HT Information Element to determine whether or not to use
protection.
The Operating Mode field has 4 possible settings: 0-3:
Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the
BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT
stations in a 20 MHz BSS
Mode 1: used if there are non-HT stations or APs using the primary or
secondary channels
Mode 2: if only HT stations are associated in the BSS and at least one
20 MHz HT station is associated.
Mode 3: used if one or more non-HT stations are associated in the BSS.
When in operating modes 1 or 3, and the Use_Protection field is 1 in the
Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or
CTS-to-Self.
By default, CTS-to-self is the preferred protection mechanism for less
overhead and higher throughput; but using the full RTS/CTS will better
protect the inner exchange from interference, especially in
highly-congested environment.
For 6000 series WIFI NIC, RTS/CTS protection mechanism is the
recommended choice for HT traffic based on the HW design.

to a kernel crash. This patch trades an easy to trigger crash in AP
mode for an unlikely race condition. According to Michael, the real
fix would be to allow set_tim() to sleep, since b43 is not the only
driver that needs to sleep in all callbacks.

xfrm: SAD entries do not expire correctly after suspend-resume
This fixes the following bug in the current implementation of
net/xfrm: SAD entries timeouts do not count the time spent by the machine
in the suspended state. This leads to the connectivity problems because
after resuming local machine thinks that the SAD entry is still valid, while
it has already been expired on the remote server.
The cause of this is very simple: the timeouts in the net/xfrm are bound to
the old mod_timer() timers. This patch reassigns them to the
CLOCK_REALTIME hrtimer.
I have been using this version of the patch for a few months on my
machines without any problems. Also run a few stress tests w/o any
issues.
This version of the patch uses tasklet_hrtimer by Peter Zijlstra
(commit 9ba5f0).
This patch is against 2.6.31.4. Please CC me.

net/compat_ioctl: support SIOCWANDEV
This adds compat_ioctl support for SIOCWANDEV, which has
always been missing.
The definition of struct compat_ifreq was missing an
ifru_settings fields that is needed to support SIOCWANDEV,
so add that and clean up the whitespace damage in the
struct definition.

ipv6: udp: Optimise multicast reception
IPV6 UDP multicast rx path is a bit complex and can hold a spinlock
for a long time.
Using a small (32 or 64 entries) stack of socket pointers can help
to perform expensive operations (skb_clone(), udp_queue_rcv_skb())
outside of the lock, in most cases.
