We can drop the use of bond->lock for mutual exclusion in
bond_3ad_update_lacp_rate and use RTNL in the sysfs store function
instead. This way we'll prevent races with mode change and interface
up/down as well as simplify update_lacp_rate by removing the check for
port->slave because it'll always be initialized (done while enslaving
with RTNL). This change will also help in the future removal of reader
bond->lock from bond_enslave.

This patch aims to remove a use of the bond->lock for mutual exclusion
which will later allow easier migration to RCU of the users of this
functionality. We use RTNL as a synchronizing mechanism since it's
always held when send_peer_notif is set, and when it is decremented from
the notifier function. We can also drop some locking, and fix the
leakage of the send_peer_notif counter.

Fix xgmac_set_rx_mode to handle several conditions that were not handled
correctly as Lennert Buytenhek describes:
If we have, say, 100 unicast addresses, and 5 multicast addresses, the
unicast address count check will evaluate to true, and set use_hash to
true. The multicast address check will however evaluate to false, and
use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't
be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true
from the unicast check, netdev_for_each_mc_addr() will program the
multicast addresses into the hash table instead of using the MAC
address registers, but since the HMC bit wasn't set, the hash table
won't be checked for multicast addresses on receive, and we'll stop
receiving multicast packets entirely.
Also, there is no code that zeroes out MAC address registers reg..31
at the end of this function, meaning that under the right conditions,
unicast/multicast addresses that were previously in the filter but
were then deleted won't be cleared out.

Fix the amount of sent bytes reported to BQL by reporting the
number of bytes on wire in the xmit routine, and recording that
value for each skb in order to be correctly confirmed on Tx
confirmation cleanup.
Reporting skb->len to BQL just before exiting xmit is not correct
due to possible insertions of TOE block and alignment bytes in the
skb->data, which are being stripped off by the controller before
transmission on wire. This led to mismatch of (incorrectly)
reported bytes to BQL b/w xmit and Tx confirmation, resulting in
Tx timeout firing, for the h/w tx timestamping acceleration case.
There's no easy way to obtain the number of bytes on wire in the Tx
confirmation routine, so skb->cb is used to convey that information
from xmit to Tx confirmation, for now (as proposed by Eric). Revived
the currently unused GFAR_CB() construct for that purpose.

We're using it currently to verify if we have vlans before getting the tag
from the skb we're about to send. It's useless because the vlan_get_tag()
verifies if the skb has the tag (and returns an error if not), and we can
receive tagged skbs only if we *already* have vlans.
Plus, the current RCUed implementation is kind of useless anyway - the we
can remove the last vlan in the moment we return from the function.
So remove the only usage of it and the whole function.

====================
Please accept this batch of updates intended for the 3.12 stream.
For the mac80211 bits, Johannes says this:
"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."
Also for mac80211:
"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."
And for iwlwifi:
"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."
Regarding the Bluetooth bits, Gustavo says:
"Patches to 3.12, here we have:
* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"
For the NFC bits, Samuel says:
"With this one we have:
- A few pn533 improvements and minor fixes. Testing our pn533 driver
against Google's NCI stack triggered a few issues that we fixed now.
We also added Tx fragmentation support to this driver.
- More NFC secure element handling. We added a GET_SE netlink command
for getting all the discovered secure elements, and we defined 2
additional secure element netlink event (transaction and connectivity).
We also fixed a couple of typos and copy-paste bugs from the secure
element handling code.
- Firmware download support for the pn544 driver. This chipset can enter a
special mode where it's waiting for firmware blobs to replace the
already flashed one. We now support that mode."
With repect to the ath tree, Kalle says:
"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.
For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."
I also pulled the wireless tree into wireless-next to support a
request from Johannes. On top of all that, there are the usual
sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.

If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest
does not have to calculate the checksums on all received packets. This
is pretty much the same feature as RX checksum offloading on real
network cards, so the virtio-net driver should report this by setting
the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she
can see whether the virtio-net interface has to calculate RX checksums
or not.

Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.
(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)

Currently, if there are vlans on top of bond, alb_send_learning_packets()
will never send LPs from the bond itself (i.e. untagged), which might leave
untagged clients unupdated.
Also, the 'circular vlan' logic (i.e. update only MAX_LP_BURST vlans at a
time, and save the last vlan for the next update) is really suboptimal - in
case of lots of vlans it will take a lot of time to update every vlan. It
is also never called in any hot path and sends only a few small packets -
thus the optimization by itself is useless.
So remove the whole current_alb_vlan/MAX_LP_BURST logic from
alb_send_learning_packets(). Instead, we'll first send a packet untagged
and then traverse the upper dev list, sending a tagged packet for each vlan
found. Also, remove the MAX_LP_BURST define - we already don't need it.

Currently, bond_has_this_ip() is aware only of vlan upper devices, and thus

Currently, bond_arp_send_all() is aware only of vlans, which breaks
configurations like bond <- bridge (or any other 'upper' device) with IP
(which is quite a common scenario for virt setups).
To fix this we convert the bond_arp_send_all() to first verify if the rt
device is the bond itself, and if not - to go through its list of upper
vlans and their respectiv upper devices (if the vlan's upper device matches
- tag the packet), if still not found - go through all of our upper list
devices to see if any of them match the route device for the target. If the
match is a vlan device - we also save its vlan_id and tag it in
bond_arp_send().
Also, clean the function a bit to be more readable.

Jeff Kirsher says:
====================
This series contains updates to ixgbe.
Jacob provides a fix for 82599 devices where it can potentially keep link
lights up when the adapter has gone down.
Mark provides a fix to resolve the possible use of uninitialized memory
by checking the return value on EEPROM reads.
Don provides 2 patches, one to fix a issue where we were traversing the
Tx ring with the value of IXGBE_NUM_RX_QUEUES which currently happens
to have the correct value but this is misleading. A change later, could
easily make this no longer correct so when traversing the Tx ring, use
netdev->num_tx_queues. His second patch does some minor clean ups of log
messages.
Emil provides the remaining ixgbe patches. First he fixes the link test
where forcing the laser before the link check can lead to inconsistent
results because it does not guarantee that the link will be negotiated
correctly. Then he initializes the message buffer array to 0 in order
to avoid using random numbers from the memory as a MAC address for the
VF. Emil also fixes the read loop for the I2C data to account for the
offset for SFP+ modules. Lastly, Emil provides several patches to add
support for QSFP modules where 1Gbps support is added as well as support
for older QSFP active direct attach cables which pre-date SFF-8436 v3.6.

This adds support for the EF10 network controller architecture and the
SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the
driver version to 4.0.
New features in the SFC9100 family include:
- Flexible allocation of internal resources to PCIe physical and virtual
functions under firmware control
- RX event merging to reduce DMA writes at high packet rates
- Integrated RX timestamping
- PIO buffers for lower TX latency
- Firmware-driven data path that supports additional offload features
and filter types
- Delivery of packets between functions and to multiple recipients,
allowing firmware to implement a vswitch
- Multiple RX flow hash (RSS) contexts with their own hash keys and
indirection tables
- 40G MAC (single port only)
...not all of which are enabled in this initial driver or the initial

On EF10, the firmware will initiate a queue flush in certain

If driver will fail to allocate all queues, it will shrink the number of
queues and move the storage queue to its correct place (i.e., the last
queue among the newly supported number).
When changing the pointers of the new location of the FCoE queue, we need
to pay special attention to the aggregations pointer - that memory is allocated
during probe and released upon driver removal. Current implementation has 2
pointers pointing to the same chunk of allocated memory, meaning upon removal
there will be two kfree() of the same chunk while the other won't be released.

The Huntington MC will reject all MCDI requests after an MC reboot until it sees
one with the NOT_EPOCH flag clear. This flag is set by default for all requests,
and then cleared on the first request after we detect that an MC reboot has
occurred.
The old MCDI_STATUS_DELAY_COUNT gave a timeout of 10ms, which was not long enough

while calling efx_mcdi_poll_reboot() from the loop in efx_mcdi_ev_death().

Various hardware statistics that are available for Siena are
unavailable or meaningless for Falcon. Huntington adds further to the
NIC-type-specific statistics, as it has different MAC blocks from
Falcon/Siena.
All NIC types still provide most statistics by DMA, and use
little-endian byte order.
Therefore:
1. Add some general utility functions for reporting hardware statistics,
efx_nic_describe_stats() and efx_nic_update_stats().
2. Add an efx_nic_type::describe_stats operation to get the number and
names of statistics, implemented using efx_nic_describe_stats()
3. Change efx_nic_type::update_stats to store the core statistics
(struct rtnl_link_stats64) or full statistics (array of u64) in a
caller-provided buffer. Use efx_nic_update_stats() to aid in the
implementation.
4. Rename struct efx_ethtool_stat to struct efx_sw_stat_desc and
EFX_ETHTOOL_NUM_STATS to EFX_ETHTOOL_SW_STAT_COUNT.
5. Remove efx_nic::mac_stats and struct efx_mac_stats.
