We are going to prevent the device from generating learning
notifications for a port that was configured with learning disabled.
Since learning configuration is done per {Port, VID} we need to apply
the port's learning configuration for any VID that is added to the
bridge port's VLAN filter list.
When a VID is added to the VLAN filter list of a VLAN-aware bridge port,
configure the {Port, VID} learning status according to the port's
configuration. When the VID is removed, disable learning for the {Port,
VID}.

Commit 05978481e7 ("mlxsw: spectrum: Create PVID vPort before
registering netdevice") removed __mlxsw_sp_port_vlans_del() from the
init sequence of the driver, which forced it to be non-symmetric with
regards to __mlxsw_sp_port_vlans_add().
Make both functions symmetric as the constraint no longer exists.

Up until now a learning session ended whenever the number of queried
records was zero. This turned out to be problematic in situations where
a large number of MACs (48K) had to be processed by the switch driver,
as RTNL mutex is held during the learning session.
Instead, limit the number of FDB records that can be processed in a
session to 64. This means that every time the device is queried for
learning notifications (currently, every 100ms), up to 64 records will
be processed by the switch driver.

David Howells says:
====================
rxrpc: Miscellaneous improvements
Here are some improvements that are part of the AF_RXRPC rewrite. They
need to be applied on top of the just posted cleanups.
(1) Set the connection expiry on the connection becoming idle when its
last currently active call completes rather than each time put is
called.
This means that the connection isn't held open by retransmissions,
pings and duplicate packets. Future patches will limit the number of
live connections that the kernel will support, so making sure that old
connections don't overstay their welcome is necessary.
(2) Calculate packet serial skew in the UDP data_ready callback rather
than in the call processor on a work queue. Deferring it like this
causes the skew to be elevated by further packets coming in before we
get to make the calculation.
(3) Move retransmission of the terminal ACK or ABORT packet for a
connection to the connection processor, using the terminal state
cached in the rxrpc_connection struct. This means that once last_call
is set in a channel to the current call's ID, no more packets will be
routed to that rxrpc_call struct.

rxrpc: Cleanups
Here are some cleanups for the AF_RXRPC rewrite:
(1) Remove some unused bits.
(2) Call releasing on socket closure is now done in the order in which
calls progress through the phases so that we don't miss a call
actively moving list.
(3) The rxrpc_call struct's channel number field is redundant and replaced
with accesses to the masked off cid field instead.
(4) Use a tracepoint for socket buffer accounting rather than printks.
Unfortunately, since this would require currently non-existend
arch-specific help to divine the current instruction location, the
accounting functions are moved out of line so that
__builtin_return_address() can be used.

This series contains several low level and API updates for mlx5 core
commands interface and mlx5_ifc.h to be shared as base code for net-next and
rdma mlx5 4.9 submissions.
From Saeed, ten patches that refactors old layouts of firmware commands which
were manually generated before we introduced the mlx5_ifc, now all of the firmware
commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old
manually generated structures. Plus to those ten patches, we add two patches
that unifies mlx5 commands execution interface and improve the driver log messages
in that area.
From Hadar and Ilya, added the needed hardware bits and infrastructure for
minimum inline headers setting and encap/decap commands and capabilities,
needed for E-Switch offloads.
This series applies on top latest net-next and rdma/master, and smoothly merges with
the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch.

Perform terminal call ACK/ABORT retransmission in the connection processor
rather than in the call processor. With this change, once last_call is
set, no more incoming packets will be routed to the corresponding call or
any earlier calls on that channel (call IDs must only increase on a channel
on a connection).
Further, if a packet's callNumber is before the last_call ID or a packet is
aimed at successfully completed service call then that packet is discarded
and ignored.

Calculate the serial number skew in the data_ready handler when a packet
has been received and a connection looked up. The skew is cached in the
sk_buff's priority field.
The connection highest received serial number is updated at this time also.
This can be done without locks or atomic instructions because, at this
point, the code is serialised by the socket.
This generates more accurate skew data because if the packet is offloaded
to a work queue before this is determined, more packets may come in,
bumping the highest serial number and thereby increasing the apparent skew.
This also removes some unnecessary atomic ops.

Set the connection expiry time when a connection becomes idle rather than
doing this in rxrpc_put_connection(). This makes the put path more

outstanding calls because active workqueue items needs to be given a ref).

never gets used.

When clearing a socket, we should clear the securing-in-progress list
first, then the accept queue and last the main call tree because that's the

call could possibly move from sequreq to acceptq whilst we're clearing up.
