bridge: fdb: converge fdb searching functions into one
Before this patch we had 3 different fdb searching functions which was
confusing. This patch reduces all of them to one - fdb_find_rcu(), and
two flavors: br_fdb_find() which requires hash_lock and br_fdb_find_rcu
which requires RCU. This makes it clear what needs to be used, we also
remove two abusers of __br_fdb_get which called it under hash_lock and
replace them with br_fdb_find().

====================
40GbE Intel Wired LAN Driver Updates 2017-02-11
This series contains updates to i40e and i40evf only.
Jake makes a minor change to prevent a minor bit of work, if it is not
necessary. In the case where we do not have a client, there is no need
to check the client params, so move the check till after we have ensured
we have a client. Correct a code comment which incorrectly implied
that raw_packet buffers were freed in i40e_clean_tx_ring(), so fixed
the code comment to better explain where memory is freed. Reduce the
severity and frequency of the message notifying we cleared the receive
timestamp register, since the logic has a much better detection scheme
that could detect a stalled receive timestamp register. The improved
logic was actually causing the notification message to occur more
frequently and was giving the user a false perception that a timestamp
event was missed for a valid packet, so reduce the severity from
dev_warn to dev_dbg and only fire off the message when 3 or 4 of the
RXTIME registers are stalled and get cleared within the same
watchdog event. Fixed a bug, where we were modifying the mac_filter
outside a lock when handling the addition of broadcast filters. Fix
this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters, which ensures that we do not have to remove
the filter separately and can put it back using the normal flow.
Refactored how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.
Mitch adds a sleep (without timeout) so that we wait for a reply from
the PF before we continue, since the iWarp client cannot continue until
the operation is completed. Fixed up a function which could never
return an error, to be void and cleaned up the checking of the now
null and void return value.
Scott limits the DMA sync to CPU to the actual length of the incoming
packet, versus the syncing of the entire buffer. Also reduces the
receive buffer struct (by a single pointer) and align the driver to be
more consistent with other Intel drivers with respect to packets that
span buffers.
Sudheer adds a field to track the bus number info and modified log
statements to print bus, device and function information.
Henry adds the ability to store the FEC status bits from the link up
event. Also adds the ethtool support for FEC capabilities and 25G
link types.

====================
mv88e6xxx Watchdog support
The Marvell switches have an in built watchdog over some of the
internal state machine. The watchdog can be configured to raise an
interrupt on error. The problem the watchdog found is then logged to
the kernel log.
The older switches can automagically perform a software reset when the
watchdog triggers. This just resets the internal state machine, but
leaves the switch configuration unchanged.
The 6390 family of switches cannot both raise an interrupt and
automagically perform a software reset. So the interrupt handler has
to perform the switch reset, and then re-enable the watchdog
interrupts.
This has been tested using hacked together debugfs code which allows
the "force" bit to be set, so cause a watchdog interrupt.

i40e: avoid race condition when sending filters to firmware for addition
Refactor how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.
To understand the race condition, suppose that you have a number of MAC
filters, but have not yet added any VLANs. Now, add two VLANs in rapid
succession. A possible resulting flow would look something like the
following:
(1) lock hash for add VLAN
(2) add the new MAC/VLAN combos for each current MAC filter
(3) unlock hash
(4) lock hash for filter sync
(5) notice that we have a VLAN, so prepare to update all MAC filters
with VLAN=-1 to be VLAN=0.
(6) move NEW and REMOVE filters to temporary list
(7) unlock hash
(8) lock hash for add VLAN
(9) add new MAC/VLAN combos. Notice that no MAC filters are currently in
the hash list, so we don't add any VLANs <--- BUG!
(10) unlock hash
(11) sync the temporary lists to firmware
(12) lock hash for post-sync
(13) move the temporary elements back to the main list
....
Because we take filters out of the main hash into temporary lists, we
introduce a narrow window where it is possible that other callers to the
list will not see some of the filters which were previously added but
have not yet been finalized. This results in sometimes dropping VLAN
additions, and could also result in failing to add a MAC address on the
newly added VLAN.
One obvious way to avoid this race condition would be to lock the entire
firmware process. Unfortunately this does not work because adminq
firmware commands take a mutex which results in a sleep while atomic
BUG(). So, we can't use the simplest approach.
An alternative approach is to simply not remove the filters from the
hash list while adding. Instead, add an i40e_new_mac_filter structure
which we will use to track added filters. This avoids the need to remove
the filter from the hash list. We'll store a pointer to the original
i40e_mac_filter, along with our own copy of the state.
We won't update the state directly, so as to avoid race with other code
that may modify the state while under the lock. We are safe to read
f->macaddr and f->vlan since these only change in two locations. The
first is on filter creation, which must have already occurred. The
second is inside i40e_correct_vlan_filters which was previously run
after creation of this object and can't be run again until after. Thus,
we should be safe to read the MAC address and VLAN while outside the
lock.
We also aren't going to run into a use-after-free issue because the only
place where we free filters is when they are marked FAILED or when we
remove them inside the sync subtask. Since the subtask has its own
critical flag to prevent duplicate runs, we know this won't happen. We
also know that the only location to transition a filter from NEW to
FAILED is inside the subtask also, so we aren't worried about that
either.
Use the wrapper i40e_new_mac_filter for additions, and once we've
finalized the addition to firmware, we will update the filter state
inside a lock, and then free the wrapper structure.
In order to avoid a possible race condition with filter deletion, we
won't update the original filter state unless it is still
I40E_FILTER_NEW when we finish the firmware sync.
This approach is more complex, but avoids race conditions related to
filters being temporarily removed from the list. We do not need the same
behavior for deletion because we always unconditionally removed the
filters from the list regardless of the firmware status.

i40e: allow i40e_update_filter_state to skip broadcast filters
Fix a bug where we modified the mac_filter_hash while outside a lock,
when handling addition of broadcast filters.
Normally, we add filters to firmware by batching the additions into
lists and issuing 1 update for every few filters. Broadcast filters are
handled differently, by instead setting the broadcast promiscuous mode
flags. In order to make sure the 1<->1 mapping of filters in our
addition array lined up with filters in the hlist tmp_add_list, we had
to remove the filter and move it back to the main hash. However, we
didn't do this under lock, which could cause consistency problems for
the list.
Fix this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters. This ensures that we don't have to remove the
filter separately, and can put it back using the normal flow.

i40e: don't warn every time we clear an Rx timestamp register
The intent of this message was to indicate to a user that we might have
missed a timestamp event for a valid packet. The original method of
detecting the missed events relied on waiting until all 4 registers were
filled.
A recent commit
d55458c0cd7a5 ("i40e: replace PTP Rx timestamp hang
logic") replaced this logic with much better detection
scheme that could detect a stalled Rx timestamp register even when other
registers were still functional.
The new logic means that a message will be displayed almost as soon as
a timestamp for a dropped frame occurs. This new logic highlights that
the hardware will attempt timestamp for frames which it later decides to
drop. The most prominent example is when a multicast PTP frame is
received on a multicast address that we are not subscribed to.
Because the hardware initiates the Rx timestamp as soon as possible, it
will latch an RXTIME register, but then drop the packet.
This results in users being confused by the message as they are not
expecting to see dropped timestamp messages unless their application
also indicates that timestamps were missing.
Resolve this by reducing the severity and frequency of the displayed
message. We now only print the message if 3 or 4 of the RXTIME registers
are stalled and get cleared within the same watchdog event. This ensures
that the common case does not constantly display the message.
Additionally, since the message is likely not as meaningful to most
users, reduce the message to a dev_dbg instead of a dev_warn.
Users can still get a count of the number of timestamps dropped by
reading the ethtool statistics value, if necessary.

L2TP should use its own handler, because it really does not

Jakub Kicinski says:
====================
Netronome NFP4000 and NFP6000 PF driver
This is a base PF driver for Netronome NFP4000 and NFP6000 chips. This
series doesn't add any exciting new features, it provides a foundation
for supporting more advanced firmware applications.
Patch 1 moves a bitfield-related helper from our BPF code to the global
header.
Patch 2 renames the kernel module and adds a new main file. We were
considering 3-module approach (pf, vf, common netdev library) but
ultimately settled on a single module to keep things simple.
Patch 3 adds support for accessing chip internals. It provides a way of
configuring access windows to different parts of chip memory and issuing
pretty much any commands on chip's NoC.
Patches 4, 5, 6, 7, 8 provide support for accessing and interpreting
various hardware and firmware information structures.
Patch 9 introduces service processor (NSP) ABI. This ABI gives us
access to PHY/SFP module configuration and information as well as
methods for unloading and loading application firmware.
Patches 10 and 11 modify the existing netdev code to make it possible
to support multi-port devices (sharing a PCI device).
Patch 12 adds a new driver probe path which will be used for the PF
PCI device IDs. It utilizes the newly added infrastructure and is able
to load application FW and spawn netdevs for all card's ports.
