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

There is no good reason to not support userspace specifying the

to create a network device and pass it to a child network namespace

We have to be careful to ensure that the target network namespace
for the new device exists through the life of the call. To keep
that logic clear I have factored out the network namespace grabbing
logic into rtnl_link_get_net.
In addtion we need to continue to pass the source network namespace
to the rtnl_link_ops.newlink method so that we can find the base

ipip: Fix handling of DF packets when pmtudisc is OFF
RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel. Our implementation does exactly that.
For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set. As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.
Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.
This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set. This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur. For
hosts behind the IPIP gateway it is readily visible with a simple
ping.
This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.

be2net: Bug fix to send config commands to hardware after netdev_register
Sending config commands to be2 hardware before netdev_register is
completed, is sometimes causing the async link notification to arrive
even before the driver is ready to handle it. The commands for vlan
config and flow control settings can infact wait till be_open.
This patch takes care of that.

be2net: fix to set proper flow control on resume
If be2 goes into suspend after a user changes the flow control settings,
we are not programming them back after resume. This patch takes care of it.
We now get the flow control settings before going to suspend mode and
then apply them during resume.

mwl8k: allow for different receive descriptor formats
As the receive descriptor format is determined by the firmware running
on the hardware and not by the hardware itself, and as these
descriptor formats vary a bit between different firmware releases,
abstract out the receive descriptor init/refill/process methods, and
allow choosing between different formats at run time depending on the
chip and firmware we're running on.

mwl8k: use pci_unmap_addr{,set}() to keep track of unmap addresses on rx
Instead of reading back the unmap address from the receive
descriptor when doing receive processing, use DECLARE_PCI_UNMAP_ADDR
and pci_unmap_addr{,set}() to keep track of these addresses.

To prepare for adding support for more device types, introduce a

be stored, and change the pci id table driver data from an integer
indicating only the part number to a pointer to a mwl8k_device_info
structure.

mac80211: async station powersave handling
Some devices require that all frames to a station
are flushed when that station goes into powersave
mode before being able to send frames to that
station again when it wakes up or polls -- all in
order to avoid reordering and too many or too few
frames being sent to the station when it polls.
Normally, this is the case unless the station
goes to sleep and wakes up very quickly again.
But in that case, frames for it may be pending
on the hardware queues, and thus races could
happen in the case of multiple hardware queues
used for QoS/WMM. Normally this isn't a problem,
but with the iwlwifi mechanism we need to make
sure the race doesn't happen.
This makes mac80211 able to cope with the race
with driver help by a new WLAN_STA_PS_DRIVER
per-station flag that can be controlled by the
driver and tells mac80211 whether it can transmit
frames or not. This flag must be set according to
very specific rules outlined in the documentation
for the function that controls it.
When we buffer new frames for the station, we
normally set the TIM bit right away, but while
the driver has blocked transmission to that sta
we need to avoid that as well since we cannot
respond to the station if it wakes up due to the
TIM bit. Once the driver unblocks, we can set
the TIM bit.
Similarly, when the station just wakes up, we
need to wait until all other frames are flushed
before we can transmit frames to that station,
so the same applies here, we need to wait for
the driver to give the OK.

about used chipset interface to struct rt2x00_chip.
The new field will be used by rt2800 drivers for rt2800 library.
Also add commonly used rt2x00_intf_is_pci() and rt2x00_intf_is_usb()
