e5edb7b19f qlcnic: fix mac learning
In failover bonding case, same mac address can be programmed on other slave function.
Fw will delete old entry (original func) associated with that mac address.
Need to reporgram mac address, if failover again happen to original function.

b914c4ea92 inetpeer: __rcu annotations
Adds __rcu annotations to inetpeer
	(struct inet_peer)->avl_left
	(struct inet_peer)->avl_right

This is a tedious cleanup, but removes one smp_wmb() from link_to_pool()
since we now use more self documenting rcu_assign_pointer().

Note the use of RCU_INIT_POINTER() instead of rcu_assign_pointer() in
all cases we dont need a memory barrier.

f203af7088 be2net: Schedule/Destroy worker thread in probe()/remove() rather than open()/close()
When async mcc compls are rcvd on an i/f that is down (and so interrupts are disabled)
they just lie unprocessed in the compl queue.The compl queue can eventually get filled
up and cause the BE to lock up.The fix is to use be_worker to reap mcc compls when the
i/f is down.be_worker is now launched in be_probe() and canceled in be_remove().

853dc2e03d ipv6: fix refcnt problem related to POSTDAD state
After running this bonding setup script
    modprobe bonding miimon=100 mode=0 max_bonds=1
    ifconfig bond0 10.1.1.1/16
    ifenslave bond0 eth1
    ifenslave bond0 eth3
on s390 with qeth-driven slaves, modprobe -r fails with this message
    unregister_netdevice: waiting for bond0 to become free. Usage count = 1
due to twice detection of duplicate address.
Problem is caused by a missing decrease of ifp->refcnt in addrconf_dad_failure.
An extra call of in6_ifa_put(ifp) solves it.
Problem has been introduced with commit f2344a131b.

dev_can_checksum() incorrectly returns true in these cases:

1. The skb has both out-of-band and in-band VLAN tags and the device
   supports checksum offload for the encapsulated protocol but only with
   one layer of encapsulation.
2. The skb has a VLAN tag and the device supports generic checksumming
   but not in conjunction with VLAN encapsulation.

Rearrange the VLAN tag checks to avoid these.

cd0ea24195 gianfar: Fix crashes on RX path (Was Re: [Bugme-new] [Bug 19692] New: linux-2.6.36-rc5 crash with gianfar ethernet at full line rate traffic)
The rx_recycle queue is global per device but can be accesed by many
napi handlers at the same time, so it needs full skb_queue primitives
(with locking). Otherwise, various crashes caused by broken skbs are
possible.

This patch resolves, at least partly, bugzilla bug 19692. (Because of
some doubts that there could be still something around which is hard
to reproduce my proposal is to leave this bug opened for a month.)

7a876b0efc IPv6: Temp addresses are immediately deleted.
There is a bug in the interaction between ipv6_create_tempaddr and
addrconf_verify.  Because ipv6_create_tempaddr uses the cstamp and tstamp
from the public address in creating a private address, if we have not
received a router advertisement in a while, tstamp + temp_valid_lft might be
< now.  If this happens, the new address is created inside
ipv6_create_tempaddr, then the loop within addrconf_verify starts again and
the address is immediately deleted.  We are left with no temporary addresses
on the interface, and no more will be created until the public IP address is
updated.  To avoid this, set the expiry time to be the minimum of the time
left on the public address or the config option PLUS the current age of the
public interface.

ebb9fed2de fib: fix fib_nl_newrule()
Some panic reports in fib_rules_lookup() show a rule could have a NULL
pointer as a next pointer in the rules_list.

This can actually happen because of a bug in fib_nl_newrule() : It
checks if current rule is the destination of unresolved gotos. (Other
rules have gotos to this about to be inserted rule)

Problem is it does the resolution of the gotos before the rule is
inserted in the rules_list (and has a valid next pointer)

Fix this by moving the rules_list insertion before the changes on gotos.

A lockless reader can not any more follow a ctarget pointer, unless
destination is ready (has a valid next pointer)

f6318e5588 netfilter: fix module dependency issues with IPv6 defragmentation, ip6tables and xt_TPROXY
One of the previous tproxy related patches split IPv6 defragmentation and
connection tracking, but did not correctly add Kconfig stanzas to handle the
new dependencies correctly. This patch fixes that by making the config options
mirror the setup we have for IPv4: a distinct config option for defragmentation
that is automatically selected by both connection tracking and
xt_TPROXY/xt_socket.

The patch also changes the #ifdefs enclosing IPv6 specific code in xt_socket
and xt_TPROXY: we only compile these in case we have ip6tables support enabled.

b336369c1e macb: Don't re-enable interrupts while in polling mode
On a busy network, the macb driver could get stuck in the interrupt
handler, quickly triggering the watchdog, due to a confluence of
factors:

 1. macb_poll re-enables interrupts unconditionally, even when it will
    be called again because it exhausted its rx budget

 2. macb_interrupt only disables interrupts after scheduling
    macb_poll, but scheduling fails when macb_poll is already scheduled
    because it didn't call napi_complete

 3. macb_interrupt loops until the interrupt status register is clear,
    which will never happen in this case if the driver doesn't disable
    the RX interrupt

Since macb_interrupt runs in interrupt context, this effectively locks
up the machine, triggering the hardware watchdog.

This issue was readily reproducible on a flooded network with a
modified 2.6.27.48 kernel. The same problem appears to still be in the
2.6.36-rc8 driver code, so I am submitting this patch against that
version. I have not tested this version of the patch except to make
sure the kernel compiles.

c8716d9dc1 mac80211: Fix ibss station got expired immediately
Station addition in ieee80211_ibss_rx_queued_mgmt is not updating
sta->last_rx which is causing station expiry in ieee80211_ibss_work
path. So sta addition and deletion happens repeatedly.

The wl1251 move accidently renamed wl1251_sdio and wl1251_spi
modules to just sdio and spi. Restore proper module names.

0299a50abb ath9k: fix handling of rate control probe frames
The ath9k aggregation code was already checking the rate control probe flag
to prevent starting an aggregate frame with a sampling rate. What was missing
was closing an aggregate before adding a probing frame to it.
Without that, rate control cannot have precise control over probing, which
delays using faster rates when the channel conditions improve.

0845735e2d ath9k: fix crash in ath_update_survey_stats
If ah->curchan is uninitialized, the channel index is bogus, which leads
to invalid memory access when the cycle counters are updated.
