In sctp_auth_make_key_vector, we allocate a temporary sctp_auth_bytes
structure with kmalloc instead of the sctp_auth_create_key allocator.
Change this to sctp_auth_create_key as it is the case everywhere else,
so that we also can properly free it via sctp_auth_key_put. This makes
it easier for future code changes in the structure and allocator itself,
since a single API is consistently used for this purpose. Also, by
using sctp_auth_create_key we're doing sanity checks over the arguments.

Some multicast addresses are common to all macvlans,
so if a multicast message has a hash value collision, we
have to deliver a copy to all macvlans, adding significant
latency and possible packet drops if netdev_max_backlog
limit is hit.
Having a per macvlan hash function permits to reduce the
impact of hash collisions.

====================
Please accept this pull request intended for the 3.9 stream!
Included are a mac80211 pull, an iwlwifi pull (actually two -- one
was a fast-forward), a wl12xx pull, and a couple of Bluetooth pulls.
On mac80211, Johannes says:
"I've included
* AKM definitions from Bing,
* mesh fixes from Thomas, including a fix from him for me breaking his
patch while applying,
* channel check fix from Simon,
* an old patch from Yoni Divinsky who doesn't even work for TI any
more, to configure the WEP TX key for ARP offload etc.
* MAC ACL API from Vasanth
* a fix for the infamous chanctx_conf warning from Arnd
* from myself, a fix for my previous aggregation changes, some cleanup
and some improvements and fixes for WoWLAN"
On iwlwifi, Johannes says:
"Two small changes for iwlwifi-next, one to update all our Copyright
notices and one to provide the RX page order."
And also:
"So what I have here is some cleanups, preparations and the new MVM
(multi-virtual MAC) driver itself and (this is new) some work on the
transport API as well as a message flooding fix."
On wl12xx, Luca says:
"Lots of bugfixes and improvements in our TI wireless drivers,
including support for multi-channel. Intended for 3.9."
On Bluetooth, Gustavo says:
"This is my first pull request to 3.9. The biggest changes here are from Johan
Hedberg who made a lot of fixes in the Management interface. The issues arose
due to a new test tool we wrote and the usage of the Management interface as
default in BlueZ 5. The rest of the patches are more clean ups and small
fixes."
And also:
"Here goes another batch intended for 3.9, the majority of the patch here are
from Johan who is fixing many issues in the management interface that have
appeared lately. The rest of the patches are just small improvements, fixes
and clean ups."
Along with those are the usual variety of updates/enhancements to
the mwl8k, mwifiex, ath9k, rtlwifi, and rt2x00 drivers as well as
a few updates for the ssb and bcma busses. I don't think there are
any big headliners there.
Please let me know if there are problems!

The BCM4785 or sometimes named BMC4705 is a Broadcom SoC which a
Gigabit 5750 Ethernet core. The core is connected via PCI with the rest
of the SoC, but it uses some extension.
This core does not use a firmware or an eeprom.
Some devices only have a switch which supports 100MBit/s, this
currently does not work with this driver.
This patch was original written by Michael Buesch <m@bues.ch> and is in
OpenWrt for some years now.
This was tested on a Linksys WRT610N V1 and older versions of this patch
were tested by other people on different devices.

The mac address is already stored in the sprom structure by the
platform code of the SoC this Ethernet core is found on, it just has to
be fetched from this structure instead of accessing the nvram here.
This patch also adds a return value to indicate if a mac address could
be fetched from the sprom structure.
When CONFIG_SSB_DRIVER_GIGE is not set the header file now also declares
ssb_gige_get_macaddr().

Amir Vadai says:
====================
This series from Yan Burman adds support for unicast MAC address filtering and
ndo FDB operations. It also includes some optimizations to loopback related
decisions and checks in the TX/RX fast path and one cleanup, all in separate
patches.
Today, when adding macvlan devices, the NIC goes into promiscuous mode, since
unicast MAC filtering is not supported. With these changes, macvlan devices can
be added without the penalty of promiscuous mode.
If for some reason adding a unicast address filter fails e.g as of missing space in
the HW mac table, the device forces itself into promiscuous mode (and out of this
forced state when enough space is available).
Also, now it is possible to have bridge under multi-function configuration that include
PF and VFs. In order to use bridge over PF/VFs, VM MAC fdb entries must be added e.g.
using 'bridge fdb add' command.
Changes from v1 - based on more comments from Eric Dumazet:
* added failure handling when adding unicast address filter
Changes from v0 - based on comments from Eric Dumazet:
* Removed unneeded synchronize_rcu()
* Use kfree_rcu() instead of synchronize_rcu() + kfree()

Actual functions moved:
mlx4_replace_mac
mlx4_get_eth_qp

Currently, RX path code that does RX filtering is not optimized
and does an expensive conversion. In order to use ether_addr_equal_64bits
which is optimized for such cases, we need the MAC address kept by the device
to be in the form of unsigned char array instead of u64. Store the MAC address
as unsigned char array and convert to/from u64 out of the fast path when needed.
Side effect of this is that we no longer need priv->mac, since it's the same
as dev->dev_addr.

Currently there are relatively complex conditional checks in the fast path,
for TX loopback enabling and resulting RX filter logic.
Move elaborate if's out of data path, replace them with a single flag
for each state and update that state from appropriate places.
Also, in native (non SRIOV) mode and not in loopback or in selftest,
there is no need to try and filter out packets that HW loopback-ed,
as in native mode we do not loopback packets anymore.

skb_gso_segment() is almost always called in tx path,
except for openvswitch. It calls this function when
it receives the packet and tries to queue it to user-space.
In this special case, the ->ip_summed check inside
skb_gso_segment() is no longer true, as ->ip_summed value
has different meanings on rx path.
This patch adjusts skb_gso_segment() so that we can at least
avoid such warnings on checksum.

Some modes don't require any special carrier handling so
in these cases, the kernel can control the carrier as for
any other interface. However, some other modes, e.g. lacp,
requires more than just that, so userspace needs to control
the carrier itself.
The daemon today is ready to control it, but the kernel
still can change it based on events.
This fix so that either kernel or userspace is controlling
the carrier.

Ivan Vercera was recently backporting commit
9c13cb8bb477a83b9a3c9e5a5478a4e21294a760 to a RHEL kernel, and I noticed that,
while this patch protects the tg3 driver from having its ndo_poll_controller
routine called during device initalization, it does nothing for the driver
during shutdown. I.e. it would be entirely possible to have the
ndo_poll_controller method (or subsequently the ndo_poll) routine called for a
driver in the netpoll path on CPU A while in parallel on CPU B, the ndo_close or
ndo_open routine could be called. Given that the two latter routines tend to
initizlize and free many data structures that the former two rely on, the result
can easily be data corruption or various other crashes. Furthermore, it seems
that this is potentially a problem with all net drivers that support netpoll,
and so this should ideally be fixed in a common path.
As Ben H Pointed out to me, we can't preform dev_open/dev_close in atomic
context, so I've come up with this solution. We can use a mutex to sleep in
open/close paths and just do a mutex_trylock in the napi poll path and abandon
the poll attempt if we're locked, as we'll just retry the poll on the next send
anyway.
I've tested this here by flooding netconsole with messages on a system whos nic
driver I modfied to periodically return NETDEV_TX_BUSY, so that the netpoll tx
workqueue would be forced to send frames and poll the device. While this was
going on I rapidly ifdown/up'ed the interface and watched for any problems.
I've not found any.

Jeff Kirsher says:
====================
This series contains updates to e1000e and ixgbe. Majority of the patches
are against e1000e, where Bruce makes several cosmetic #define moves into
header files. In addition, Bruce does a cleanup of braces to resolve
checkpatch warnings (when using the strict option).
Ixgbe patches contain several fixes as well as updating the copyright. The
fixes from Josh Hay, resolved a possible NULL pointer dereference and
resolved Smatch warnings by fixing return values and memcpy parameters.
Alex provides 2 fixes, the first is to replace rmb() with
read_barrier_depends() in the Tx cleanup. The second fixes an MTU
warning when using SR-IOV which corrects the fact that we were using 1522
to test for the max frame size in ixgbe_change_mtu and 1518 in
ixgbe_set_vf_lpe. The difference was the addition of VLAN_HLEN, which we
only need to add in the case of computing a buffer size, but not a filter
size. Lastly, a patch from Emil which is based on a community patch from
Aurélien Guillaume which adds functions needed for reading SFF-8472
diagnostic data from SFP modules.

TCP Appropriate Byte Count was added by me, but later disabled.
There is no point in maintaining it since it is a potential source
of bugs and Linux already implements other better window protection
heuristics.

All in-tree ipv4 protocol implementations are now namespace
aware. Therefore all the run-time checks are superfluous.
Reject registry of any non-namespace aware ipv4 protocol.
Eventually we'll remove prot->netns_ok and this registry
time check as well.
