2571178626 net: sched: shrink struct qdisc_skb_cb to 28 bytes
We cannot make struct qdisc_skb_cb bigger without impacting IPoIB,
or increasing skb->cb[] size.

Commit e0f31d8498 ("flow_keys: Record IP layer protocol in
skb_flow_dissect()") broke IPoIB.

Only current offender is sch_choke, and this one do not need an
absolutely precise flow key.

If we store 17 bytes of flow key, its more than enough. (Its the actual
size of flow_keys if it was a packed structure, but we might add new
fields at the end of it later)

476c18850c tg3: Work around HW/FW limitations with vlan encapsulated frames
TG3 appears to have an issue performing TSO and checksum offloading
correclty when the frame has been vlan encapsulated (non-accelrated).
In these cases, tcp checksum is not correctly updated.

This patch attempts to work around this issue.  After the patch,
802.1ad vlans start working correctly over tg3 devices.

07d92d5cc9 macvlan: allow to enqueue broadcast pkt on virtual device
Since commit 412ca1550c ("macvlan: Move broadcasts into a work queue"), the
driver uses tx_queue_len of the master device as the limit of packets enqueuing.
Problem is that virtual drivers have this value set to 0, thus all broadcast
packets were rejected.
Because tx_queue_len was arbitrarily chosen, I replace it with a static limit
of 1000 (also arbitrarily chosen).

df568d8e52 scsi: Use 'depends' with LIBFC instead of 'select'.
LIBFC depends upon SCSI_FC_ATTRS and select's CRC32C.

The only alternative would be to 'select' CRC32C and all of
SCSI_FC_ATTRS direct and indirect dependencies in the Kconfig section
for every LIBFCOE user which makes little sense.

Subsequently, use 'depends' instead of 'select' for LIBFCOE too.

0d0162e7a3 net: allow macvlans to move to net namespace
I cannot move a macvlan interface created on top of a bonding interface
to a different namespace:

% ip netns add dummy0
% ip link add link bond0 mac0 type macvlan
% ip link set mac0 netns dummy0
RTNETLINK answers: Invalid argument
%

The problem seems to be that commit f939981492 ("bonding: Don't allow
bond devices to change network namespaces.") sets NETIF_F_NETNS_LOCAL
on bonding interfaces, and commit 797f87f83b ("macvlan: fix netdev
feature propagation from lower device") causes macvlan interfaces
to inherit its features from the lower device.

NETIF_F_NETNS_LOCAL should not be inherited from the lower device
by a macvlan.

f6f2332dce sparc: bpf_jit: fix support for ldx/stx mem and SKF_AD_VLAN_TAG
fix several issues in sparc BPF JIT compiler.

ldx/stx related:
. classic BPF instructions that access mem[] slots were not setting
  SEEN_MEM flag, so stack wasn't allocated. Fix that by advertising
  correct flags

. LDX/STX instructions were missing SEEN_XREG, so register value
  could have leaked to user space. Fix it.

. since stack for mem[] slots is allocated with 'sub %sp' instead
  of 'save %sp', use %sp as base register instead of %fp.

. ldx mem[0] means first slot in classic BPF which should have
  -4 offset instead of 0.

. sparc64 needs 2047 stack bias as per ABI to access stack

. emit_stmem() was using LD32I macro instead of ST32I

SKF_AD_VLAN_TAG* related:
. SKF_AD_VLAN_TAG_PRESENT must return 1 or 0 instead of '> 0' or 0
  as per classic BPF de facto standard

. SKF_AD_VLAN_TAG needs to mask the field correctly

de5944883e can: flexcan: put TX mailbox into TX_INACTIVE mode after tx-complete
After sending a RTR frame the TX mailbox becomes a RX_EMPTY mailbox. To avoid
side effects when the RX-FIFO is full, this patch puts the TX mailbox into
TX_INACTIVE mode in the transmission complete interrupt handler. This, of
course, leaves a race window between the actual completion of the transmission
and the handling of tx-complete interrupt. However this is the best we can do
without busy polling the tx complete interrupt.

25e924450f can: flexcan: implement workaround for errata ERR005829
This patch implements the workaround mentioned in ERR005829:

    ERR005829: FlexCAN: FlexCAN does not transmit a message that is enabled to
    be transmitted in a specific moment during the arbitration process.

Workaround: The workaround consists of two extra steps after setting up a
message for transmission:

Step 8: Reserve the first valid mailbox as an inactive mailbox (CODE=0b1000).
If RX FIFO is disabled, this mailbox must be message buffer 0. Otherwise, the
first valid mailbox can be found using the "RX FIFO filters" table in the
FlexCAN chapter of the chip reference manual.

Step 9: Write twice INACTIVE code (0b1000) into the first valid mailbox.

f650fb456f sfc: fix addr_list_lock spinlock use before init
Reported by Nikolay Aleksandrov.  In efx_init_port() we call
 efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
 efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
 lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
 doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
 corresponding check.

It turns out that the IF event for the P2P_DEVICE also has this
flag set, but the event should not be ignored in this scenario.
The mentioned commit caused a regression in 3.12 kernel in creation
of the P2P_DEVICE interface.

8f2b45971b brcmfmac: obtain ifp through wdev structure
For P2P_DEVICE interface the function brcmf_cfg80211_update_proto_addr_mode()
resulted in a crash, because it assumed wdev->netdev would be valid. The
ifp should be obtained through the driver vif structure which contains the
wireless_dev.

f1d56039b5 brcmfmac: conditionally compile firmware protocol source code
The host-interface can select which protocol implementation it
needs. Selecting PCIe will include the msgbuf protocol and selecting
USB and/or SDIO will include the bcdc protocol. The PCIe kconfig
option assures the dependencies for msgbuf are met, ie. HAS_DMA.

635126b7ca bridge: Allow clearing of pvid and untagged bitmap
Currently, it is possible to modify the vlan filter
configuration to add pvid or untagged support.
For example:
  bridge vlan add vid 10 dev eth0
  bridge vlan add vid 10 dev eth0 untagged pvid

The second statement will modify vlan 10 to
include untagged and pvid configuration.
However, it is currently impossible to go backwards
  bridge vlan add vid 10 dev eth0 untagged pvid
  bridge vlan add vid 10 dev eth0

Here nothing happens.  This patch correct this so
that any modifiers not supplied are removed from
the configuration.

20adfa1a81 bridge: Check if vlan filtering is enabled only once.
The bridge code checks if vlan filtering is enabled on both
ingress and egress.   When the state flip happens, it
is possible for the bridge to currently be forwarding packets
and forwarding behavior becomes non-deterministic.  Bridge
may drop packets on some interfaces, but not others.

This patch solves this by caching the filtered state of the
packet into skb_cb on ingress.  The skb_cb is guaranteed to
not be over-written between the time packet entres bridge
forwarding path and the time it leaves it.  On egress, we
can then check the cached state to see if we need to
apply filtering information.

9a72c2da69 bonding: fix div by zero while enslaving and transmitting
The problem is that the slave is first linked and slave_cnt is
incremented afterwards leading to a div by zero in the modes that use it
as a modulus. What happens is that in bond_start_xmit()
bond_has_slaves() is used to evaluate further transmission and it becomes
true after the slave is linked in, but when slave_cnt is used in the xmit
path it is still 0, so fetch it once and transmit based on that. Since
it is used only in round-robin and XOR modes, the fix is only for them.
Thanks to Eric Dumazet for pointing out the fault in my first try to fix
this.

pull request: wireless 2014-09-11

Please pull this batch of fixes intended for the 3.17 stream:

For the mac80211 bits, Johannes says:

"Two more fixes for mac80211 - one of them addresses a long-standing
issue that we only found when using vendor events more frequently;
the other addresses some bad information being reported in userspace
that people were starting to actually look at."

For the iwlwifi bits, Emmanuel says:

"I re-enable scheduled scan on firmware that contain the fix for
the bug that Linus reported.  A few trivial fixes: endianity issues,
the same DTIM period fix that I did in mac80211.  Eyal fixes a few
issues we identified with EAPOL, we now send them just as if they were
management frames, this solves interrop issues.  Johannes has another
set of trivial fixes, while Luca fixes the way we configure the filters
in the firmware. Last but not least, a new device is added by Oren."

Emmanuel was traveling, resulting in his pull to be a bit larger than
I would have liked to see at this point.  FWIW, I have asked Emmanuel
to be much more strict for any more pull requests in this cycle.

In addition to the above, Sujith Manoharan reverts an earlier ath9k
patch.  The earlier change was found to allow for the device to sleep
too long and miss beacons.
