When walking a session's packet reorder queue, use

Rearrange the unlinking skbs from the reorder queue such that it is

Fix locking issues in the pppol2tp driver which can cause a kernel
crash on SMP boxes. There were two problems:-
1. The driver was violating read_lock() and write_lock() scheduling
rules because it wasn't using softirq-safe locks in softirq
contexts. So we now consistently use the _bh variants of the lock
functions.
2. The driver was calling sk_dst_get() in pppol2tp_xmit() which was
taking sk_dst_lock in softirq context. We now call __sk_dst_get().

Most wireless drivers load their firmware at interface open time, which
generally occurs after the filesystem is available. However, the ipw drivers
load their firmware at probe time because firmware is required to read the
device MAC address. When built-in, probe happens before the filesystem is
available, hence device init will only complete successfully if the user
has made special arrangements (including firmware plus a loader in the
initramfs).
Note all this in the kconfig help text for both drivers.

This changes mac80211 to pass the burst time to conf_tx in txop
units rather than 0.1msec units. 0.1msec units are only required
by atheros hardware (according to current driver support), all
other drivers do other calculations or require the txop value.
Therefore, it results in fewer calculations and more precision
if we just pass the txop value through to the driver.

information can later be exported to userspace, for example,
and giving it access to mac80211 and drivers in general can come
in handy.

This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out. All drivers (except ath5k)
are updated to the new API, in many cases I expect that optimisations
can be done.
Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.
Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty... However, the basic rate handling will need to be moved to
the BSS conf stuff.
I do expect there to be bugs in this, especially wrt. transmit
power handling where I'm basically clueless about how it should work.

Rework the interface handling. Delete the interface structure
and replace it with a per-interface structure. This changes the
way rt2x00 handles the active interface drastically.
Copy ieee80211_bss_conf to the this rt2x00_intf structure during
the bss_info_changed() callback function. This will allow us to
reference it later, and removes the requirement for the device flag
SHORT_PREAMBLE flag which is interface specific.
Drivers receive the option to give the maximum number of virtual
interfaces the device can handle. Virtual interface support:
rt2400pci: 1 sta or 1 ap, * monitor interfaces
rt2500pci: 1 sta or 1 ap, * monitor interfaces
rt2500usb: 1 sta or 1 ap, * monitor interfaces
rt61pci: 1 sta or 4 ap, * monitor interfaces
rt73usb: 1 sta or 4 ap, * monitor interfaces
At the moment none of the drivers support AP and STA interfaces
simultaneously, this is a hardware limitation so future support
will be very unlikely.
Each interface structure receives its dedicated beacon entry,
with this we can easily work with beaconing while multiple master
mode interfaces are currently active.
The configuration handlers for the MAC, BSSID and type are
often called together since they all belong to the interface
configuration. Merge the 3 configuration calls and cleanup
the API between rt2x00lib and the drivers. While we are cleaning
up the interface configuration anyway, we might as well clean up
the configuration handler as well.

The driver should select what CRC algorithm is required
when performing a checksum on the firmware.

This introduces a big queue handling overhaul, this also
renames "ring" to "queues".
Move queue handling into rt2x00queue.c and the matching header,
use Kerneldoc to improve rt2x00 library documentation.
Access to the queues is now protected under a spinlock, this
to prevent race conditions which could corrupt the indexing
system of the queue.
Each queue entry allocates x bytes for driver/device specific data,
this cleans up the queue structure significantly and improves
code readability.
rt2500usb no longer needs 2 entries in the beacon queue to correctly
send out the guardian byte. This is now handled in the entry specific
structure.
rt61 and rt73 now use the correct descriptor size for beacon frames,
since this data is written into the registers not the entire TXD
descriptor was used but instead of a subset of it named TXINFO.
Finally this also fixes numerous other bugs related to incorrect
beacon handling or beacon related code.

This counter is valuable to determine if the system is unable
to timely return buffers to the hardware and this counter starts
to increase well before the hardware starts to drop packets. If
users experience rx_no_buffer_count increasing, they should increase
the amount of descriptors. That will provide more buffers for the
hardware and will decrease the chance of hard drops.

This patch adds kdump support to the ehea driver. As the firmware doesn't free

free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there. The arrays are
kept up-to-date during normal runtime. The crash handler fn is triggered by the
recently introduced PPC crash shutdown reg/unreg functions.

when setting up the tx descriptors for the hardware we must account for any
padding between the header and the data we might have added previously. frame
len is the length of the frame in the air (including FCS but no padding) and
buffer len is the length of the buffer (including padding, but without FCS).
changing the way ah_setup_tx_desc is called: now excluding the FCS, since it's
easier to add that in the function where we need it.
before this fix we sent trailing zero bytes after the packet (because frame len
included the padding) which was not a big problem without WEP, but with WEP
this resultes in a wrong WEP checksum and the packet is discarded - which is
how i noticed at all ;)
an easy way to run into header padding problems, btw, is to connect to a QoS
(WME) enabled access point (eg. madwifi) - QoS data frames are 2 byte longer
and will require padding.

According to one of OOPSes reported by Jann softirq can break
while skb is prepared for netif_rx. The report isn't complete,
so the real reason of the later bug could be different, but
IMHO this locking break in ax_bump is unsafe and unnecessary.

Megahertz EM1144 PCMCIA ethernet adapter needs special handling
because it has two VERS_1 tuples and the station address is in
the second one. Conversion to generic handling of these fields
broke it. Reverting that fixes the device.

This patch avoids a null pointer dereference when we read local_mac
for netconsole in configfs and shows default local mac address
value.
A null pointer dereference occurs when we call show_local_mac() via
local_mac entry in configfs before we setup the content of netpoll
using netpoll_setup().

mlx4_table_find (for FMR MPTs) requires that ICM memory already be
mapped. Before this fix, FMR allocation depended on ICM memory
already being mapped for the MPT entry. If all currently mapped
entries are taken, the find operation fails (even if the MPT ICM table
still had more entries, which were just not mapped yet).
This fix moves the mpt find operation to fmr_enable, to guarantee that
any required ICM memory mapping has already occurred.

When ARP completes due to a request rather than a reply the neighbor is
marked NUD_STALE instead of reachable (see arp_process()). The handler
for the resulting netevent needs to check also for NUD_STALE.
Failure to use the arp entry can cause RDMA connection failures.

Reading the ID register does not always return the correct ID
from the device, so we retry several times to see if we get
a correct value.
These failures seem to be excaserbated by the speed of the

and then the data cycle).
