15e79f24b6 ixgbe: initialize interrupt throttle rate
This commit dropped the setting of the default interrupt throttle rate.

    ixgbe: Introduce MSI-X queue vector code

The following patch adds it back.  Without this the default value of 0
causes the performance of this card to be awful.  Restoring these to the
default values yields much better performance.

This regression has been around since 2.6.25.

e000ea1312 net/usb/pegasus: avoid hundreds of diagnostics
Make the "pegasus" driver scream less loudly in the face of
problems as it initializes, avoiding hundreds of messages:

 - ratelimit some key error messages
 - avoid some spurious diagnostics caused by strange codeflow

And fix one instance of goofy indentation.

37b08e34a9 ipsec: Fix deadlock in xfrm_state management.
Ever since commit 4c563f7669
("[XFRM]: Speed up xfrm_policy and xfrm_state walking") it is
illegal to call __xfrm_state_destroy (and thus xfrm_state_put())
with xfrm_state_lock held.  If we do, we'll deadlock since we
have the lock already and __xfrm_state_destroy() tries to take
it again.

Fix this by pushing the xfrm_state_put() calls after the lock
is dropped.

06770843c2 ipv: Re-enable IP when MTU > 68
Re-enable IP when the MTU gets back to a valid size. 

This patch just checks if the in_dev is NULL on a NETDEV_CHANGEMTU event
and if MTU is valid (bigger than 68), then re-enable in_dev. 

Also a function that checks valid MTU size was created.

9d7d74029e net/xfrm: Use an IS_ERR test rather than a NULL test
In case of error, the function xfrm_bundle_create returns an ERR
pointer, but never returns a NULL pointer. So a NULL test that comes
after an IS_ERR test should be deleted.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@match_bad_null_test@
expression x, E;
statement S1,S2;
@@
x =  xfrm_bundle_create(...)

773b4e02be ath9: Fix ath_rx_flush_tid() for IRQs disabled kernel warning message.
This patch addresses an issue with the locking order. ath_rx_flush_tid()
uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211.

As node clean up is still pending with ath9k and this problematic portion
of the code is expected to change anyway, thinking of a proper fix may not
be worthwhile. So having this interim fix helps the users to get rid of the
kernel warning message.

Pasted the kernel warning message for reference.

Updating sc_keytype multiple times when groupwise and pairwise
ciphers are different results in incorrect pairwise key type
assumed for TX control and normal ping fails. This works fine
for cases where both groupwise and pairwise ciphers are same.

2b58b20939 mac80211: Fix debugfs union misuse and pointer corruption
debugfs union in struct ieee80211_sub_if_data is misused by including a
common default_key dentry as a union member. This ends occupying the same
memory area with the first dentry in other union members (structures;
usually drop_unencrypted). Consequently, debugfs operations on
default_key symlinks and drop_unencrypted entry are using the same
dentry pointer even though they are supposed to be separate ones. This
can lead to removing entries incorrectly or potentially leaving
something behind since one of the dentry pointers gets lost.

Fix this by moving the default_key dentry to a new struct
(common_debugfs) that contains dentries (more to be added in future)
that are shared by all vif types. The debugfs union must only be used
for vif type-specific entries to avoid this type of pointer corruption.

667d41008e orinoco: Multicast to the specified addresses
When multicasting the driver sets the number of group addresses using
the count from the previous set multicast command. In general this means
you have to set the multicast addresses twice to get the behaviour you
want.

If we were multicasting, and reduce the number of addresses we are
multicasting to, then the driver would write uninitialised data from the
stack into the group addresses to multicast to.

Only write the multicast addresses we have specifically set.

7c19a3d280 net: Unbreak userspace usage of linux/mroute.h
Nothing in linux/pim.h should be exported to userspace.

This should fix the XORP build failure reported by
Jose Calhariz, the debain package maintainer.

Nothing originally in linux/mroute.h was exported to userspace
ever, but some of this stuff started to be when it was moved into
this new linux/pim.h, and that was wrong.  If we didn't provide these
definitions for 10 years we can reasonably expect that applications
defined this stuff locally or used GLIBC headers providing the
protocol definitions.  And as such the only result of this can
be conflict and userland build breakage.

currently we can use a sleeping qdisc with the lock of noop_qdisc.

edcfe5f7e3 forcedeth: fix checksum flag
Fix the checksum feature advertised in device flags.  The hardware support
TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers).
However, the kernel feature flags do not distinguish IPv6 with/without
extension headers.

Therefore, the driver needs to use NETIF_F_IP_CSUM instead of
NETIF_F_HW_CSUM since the latter includes all IPv6 packets.

A future patch can be created to check for extension headers and perform
software checksum calculation.

45e15bb734 ibmveth: fix bad UDP checksums
This patch fixes a ibmveth bug where bad UDP checksums are being transmitted
when checksum offloading is enabled.
The hypervisor does checksum offloading only on TCP packets, so ibmveth calls
skb_checksum_help() for any other protocol.  The bug happens because
the packet is being modified after the DMA map, so we would need a memory
barrier before making the hypervisor call.  Reordering the code so that the
DMA map happens after skb_checksum_help() has the additional advantage of
fixing a DMA map leak if skb_checksum_help() where to fail.

82c26a9d11 atl1: disable TSO by default
The atl1 driver is causing stalled connections and file corruption
whenever TSO is enabled.  Two examples are here:

http://lkml.org/lkml/2008/7/15/325
http://lkml.org/lkml/2008/8/18/543

Disable TSO by default until we can determine the source of the
problem.

While passing a qdisc root lock to gen_new_estimator() and
gen_replace_estimator() dev could be deactivated or even before
grafting proper root qdisc as qdisc_sleeping (e.g. qdisc_create), so
using qdisc_root_lock() is not enough. This patch adds
qdisc_root_sleeping_lock() for this, plus additional checks, where
necessary.
