bonding: alternate agg selection policies for 802.3ad
This patch implements alternative aggregator selection policies
for 802.3ad. The existing policy, now termed "stable," selects the active
aggregator by greatest bandwidth, and only reselects a new aggregator
if the active aggregator is entirely disabled (no more ports or all ports
down).
This patch adds two new policies: bandwidth and count, selecting
the active aggregator by total bandwidth (like the stable policy) or by
the number of ports in the aggregator, respectively. These two policies
also differ from the stable policy in that they will reselect the active
aggregator when availability-related changes occur in the bond (e.g.,
link state change).
This permits "gang failover" within 802.3ad, allowing redundant
aggregators along parallel paths to always maintain the "best" aggregator
as the active aggregator (rather than having to wait for the active to
entirely fail).
This patch also updates the driver version to 3.5.0.

bonding: send IPv6 neighbor advertisement on failover
This patch adds better IPv6 failover support for bonding devices,
especially when in active-backup mode and there are only IPv6 addresses
configured, as reported by Alex Sidorenko.
- Creates a new file, net/drivers/bonding/bond_ipv6.c, for the
IPv6-specific routines. Both regular bonds and VLANs over bonds
are supported.
- Adds a new tunable, num_unsol_na, to limit the number of unsolicited
IPv6 Neighbor Advertisements that are sent on a failover event.
Default is 1.
- Creates two new IPv6 neighbor discovery functions:
ndisc_build_skb()
ndisc_send_skb()
These were required to support VLANs since we have to be able to
add the VLAN id to the skb since ndisc_send_na() and friends
shouldn't be asked to do this. These two routines are basically
__ndisc_send() split into two pieces, in a slightly different order.
- Updates Documentation/networking/bonding.txt and bumps the rev of bond
support to 3.4.0.
On failover, this new code will generate one packet:
- An unsolicited IPv6 Neighbor Advertisement, which helps the switch
learn that the address has moved to the new slave.
Testing has shown that sending just the NA results in pretty good
behavior when in active-back mode, I saw no lost ping packets for example.

It turns out that if you listen on a multicast address an unsubscribe
packet is sent when the network device goes down. If you shutdown
the network namespace without carefully cleaning up this can trigger
the unsubscribe packet to be sent over the loopback interface while
the network namespace is going down.
All of which is fine except when we drop the packet and forget to
free it leaking the skb and the dst entry attached to. As it
turns out the dst entry hold a reference to the idev which holds
the dev and keeps everything from being cleaned up. Yuck!
By fixing my earlier thinko and add the needed kfree_skb and everything
cleans up beautifully.

code which assumes that at least the loopback driver is present.
Therefore to avoid magic initcall ordering hackery that is hard

that the loopback device is the first device registered and
the last network device to go away.

* an entry struct which holds all current information together,
* elementary functions to fill in and process these structures.
Entry structs are arranged as FIFO for the following reason: RFC 4340
specifies that if multiple options of the same type are present, they
are processed in the order of their appearance in the packet; which
means that this order needs to be preserved in the local data
structure (the later insertion code also respects this order).
The struct list_head has been chosen for the following reasons: the most
frequent operations are
* add new entry at tail (when receiving Change or setting socket
options);
* delete entry (when Confirm has been received);
* deep copy of entire list (cloning from listening socket onto
request socket).
The NN value has been set to 64 bit, which is a currently sufficient
upper limit (Sequence Window feature has 48 bit).

SA defined in this fashion will carry all traffic including initial

mac80211: Change WARN_ON to WARN_ON_ONCE
A warning would be printed for every packet that
is transmitted if the rate control information isn't
setup. Change this to WARN_ON_ONCE.

ath9k: Allow user to change tx power when asked
We were also changing tx power even when we were not asked to,
this enforces the change only when we are asked nicely. When
not asked we simply try to use the max power, we don't tx power
at all for rate control.

ath9k: enable RX interrupt mitigation
This enables hardware interrupt mitigation on RX.
It should alleviate system interrupt load intelligently.

ath9k: remove pointless sc_txintrperiod and spin_lock_bh on tx prepare
sc_txintrperiod is currently set to 0 and never updated. We won't
be using this, if anything we will consider using TX interrupt
mitigation but that is different and not yet tested. So remove
sc_txintrperiod and the pointless spin_lock_bh() on tx prepare.

mac80211: make use of regulatory tx power settings on change of tx power
We do not know what max power to allow until a device is targeting
a channel, therefore only allow changing tx power if a channel is defined.
Also make use of the channel's max power setting as defined by
regulatory rules before allowing the user to use the requested power
setting. If the user asked us to figure it out we use the max allowed
by regulatory.

There is quite a lot of overlap in definitions between these headers...
