Commit 05978481 ("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.

Mellanox mlx5 core driver updates 2016-08-24

This series contains some low level and API updates for mlx5 core
driver interface and mlx5_ifc.h, plus mlx5 LAG core driver support,
to be shared as base code for net-next and rdma mlx5 4.9 submissions.

From Alex and Artemy, Update mlx5_ifc for modify RQ and XRC bits.

From Noa, Expose mlx5 link modes so they can be used in RDMA tree for rdma tools.

From Aviv, LAG support needed for RDMA.
    - Add needed hardware structures, layouts and interface
    - mlx5 core driver LAG implementation
    - Introduce mlx5 core driver LAG API for mlx5_ib

From Maor, add two low level patches for mlx5 hardware sniffer QP
infrastructure bits and capabilities, plus added the namespace for sniffer
steering tables.  Needed for RDMA subtree.

====================
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.

When we disable SRIOV, we used to unregister the netdev but wasn't
freed. But next time when the same netdev is registered, since the state
was in 'NETREG_UNREGISTERED', we used to hit BUG_ON in register_netdevice,
where it expects the state to be 'NETREG_UNINITIALIZED'.

Alloc netdev and register them while configuring SRIOV, and free them
when SRIOV is disabled. Also added a new function to setup ethernet
properties instead of using ether_setup. Set carrier off by default,
since we don't have to do any transmit on the interface.
