701ef3e6c7 sctp: remove the typedef sctp_scope_policy_t
This patch is to remove the typedef sctp_scope_policy_t and keep
it's members as an anonymous enum.

It is also to define SCTP_SCOPE_POLICY_MAX to replace the num 3
in sysctl.c to make codes clear.

2d1611aff3 net: stmmac: Add Adaptrum Anarion GMAC glue layer
Before the GMAC on the Anarion chip can be used, the PHY interface
selection must be configured with the DWMAC block in reset.

This layer covers a block containing only two registers. Although it
is possible to model this as a reset controller and use the "resets"
property of stmmac, it's much more intuitive to include this in the
glue layer instead.

At this time only RGMII is supported, because it is the only mode
which has been validated hardware-wise.

only report up to 4G tx,rx status, which will be wrapped to 0 when the

Therefore, it makes hard for network diagnostic tool to get reliable

234709336b Merge branch 'phylink-and-sfp-support'
Russell King says:

====================
phylink and sfp support

This patch series introduces generic support for SFP sockets found on
various Marvell based platforms.  The idea here is to provide common
SFP socket support which can be re-used by network drivers as
appropriate, rather than each network driver having to re-implement
SFP socket support.

SFP sockets typically use other system resources, eg, I2C buses to read
identifying information, and GPIOs to monitor socket state and control
the socket.  Meanwhile, some network drivers drive multiple ethernet
ports from one instantiation of the driver.

It is not desirable to block the initialisation of a network driver
(thus denying other ports from being operational) if the resources
for the SFP socket are not yet available.  This means that an element
of independence between the SFP support code and the driver is
required.

More than that, SFP modules effectively bring hotplug PHYs to
networking - SFP copper modules normally contain a standard PHY
accessed over the I2C bus, and it is desirable to read their state
so network drivers can be appropriately configured.

To add to the complexity, SFP modules can be connected in at least
two places:

1. Directly to the serdes output of a MAC with no intervening PHY.
   For example:

     mvneta ----> SFP socket

2. To a PHY, for example:

     mvpp2 ---> PHY ---> copper
                 |
                 `-----> SFP socket

This code supports both setups, although it's not fully implemented
with scenario (2).

Moreover, the link presented by the SFP module can be one of the
10Gbase-R family (for SFP+ sockets), SGMII or 1000base-X (for SFP
sockets) depending on the module, and network drivers need to
reconfigure themselves accordingly for the link to come up.

For example, if the MAC is configured for SGMII and a fibre module
is plugged in, the link won't come up until the MAC is reconfigured
for 1000base-X mode.

The SFP code manages the SFP socket - detecting the module, reading
the identifying information, and managing the control and status
signals.  Importantly, it disables the SFP module transmitter when
the MAC is down, so that the laser is turned off (but that is not
a guarantee.)

phylink provides the mechanisms necessary to manage the link modes,
based on the SFP module type, and supports hot-plugging of the PHY
without needing the MAC driver to be brought up and down on
transitions.  phylink also supports the classical static PHY and
fixed-link modes.

I currently (but not included in this series) have code to convert
mvneta to use phylink, and the out of tree mvpp2x driver.  I have
nothing for the mvpp2 driver at present as that driver is only
recently becoming functional on 10G hardware, and is missing a lot
of features that are necessary to make things work correctly.

7397005545 sfp: add SFP module support
Add support for SFP hotpluggable modules via sfp-bus and phylink.
This supports both copper and optical SFP modules, which require
different Serdes modes in order to properly negotiate the link.

Optical SFP modules typically require the Serdes link to be talking
1000BaseX mode - this is the gigabit ethernet mode defined by the
802.3 standard.

Copper SFP modules typically integrate a PHY in the module to convert
from Serdes to copper, and the PHY will be configured by the vendor
to either present a 1000BaseX Serdes link (for fixed 1000BaseT) or a
SGMII Serdes link.  However, this is vendor defined, so we instead
detect the PHY, switch the link to SGMII mode, and use traditional
PHY based negotiation.

9525ae8395 phylink: add phylink infrastructure
The link between the ethernet MAC and its PHY has become more complex
as the interface evolves.  This is especially true with serdes links,
where the part of the PHY is effectively integrated into the MAC.

Serdes links can be connected to a variety of devices, including SFF
modules soldered down onto the board with the MAC, a SFP cage with
a hotpluggable SFP module which may contain a PHY or directly modulate
the serdes signals onto optical media with or without a PHY, or even
a classical PHY connection.

Moreover, the negotiation information on serdes links comes in two
varieties - SGMII mode, where the PHY provides its speed/duplex/flow
control information to the MAC, and 1000base-X mode where both ends
exchange their abilities and each resolve the link capabilities.

This means we need a more flexible means to support these arrangements,
particularly with the hotpluggable nature of SFP, where the PHY can
be attached or detached after the network device has been brought up.

Ethtool information can come from multiple sources:
- we may have a PHY operating in either SGMII or 1000base-X mode, in
  which case we take ethtool/mii data directly from the PHY.
- we may have a optical SFP module without a PHY, with the MAC
  operating in 1000base-X mode - the ethtool/mii data needs to come
  from the MAC.
- we may have a copper SFP module with a PHY whic can't be accessed,
  which means we need to take ethtool/mii data from the MAC.

Phylink aims to solve this by providing an intermediary between the
MAC and PHY, providing a safe way for PHYs to be hotplugged, and
allowing a SFP driver to reconfigure the serdes connection.

Phylink also takes over support of fixed link connections, where the
speed/duplex/flow control are fixed, but link status may be controlled
by a GPIO signal.  By avoiding the fixed-phy implementation, phylink
can provide a faster response to link events: fixed-phy has to wait for
phylib to operate its state machine, which can take several seconds.
In comparison, phylink takes milliseconds.

IP: cleanup LSRR option processing

The __ip_options_echo() function expect a valid dst entry in skb->dst;

patches cleanup the current code keeping arund skb->dst for __ip_options_echo's
sake.

a1e155ece1 IP: do not modify ingress packet IP option in ip_options_echo()
While computing the response option set for LSRR, ip_options_echo()
also changes the ingress packet LSRR addresses list, setting
the last one to the dst specific address for the ingress packet
- via memset(start[ ...
The only visible effect of such change - beyond possibly damaging
shared/cloned skbs - is modifying the data carried by ICMP replies
changing the header information for reported the ingress packet,
which violates RFC1122 3.2.2.6.
All the others call sites just ignore the ingress packet IP options
after calling ip_options_echo()
Note that the last element in the LSRR option address list for the
reply packet will be properly set later in the ip output path
via ip_options_build().
This buggy memset() predates git history and apparently was present
into the initial ip_options_echo() implementation in linux 1.3.30 but
still looks wrong.

The removal of the fib_compute_spec_dst() call will help
completely dropping the skb->dst usage by __ip_options_echo() with a
later patch.

9b0d4446b5 net: sched: avoid atomic swap in tcf_exts_change
tcf_exts_change is always called on newly created exts, which are not used
on fastpath. Therefore, simple struct copy is enough.

705c709126 net: sched: cls_u32: no need to call tcf_exts_change for newly allocated struct
As the n struct was allocated right before u32_set_parms call,
no need to use tcf_exts_change to do atomic change, and we can just
fill-up the unused exts struct directly by tcf_exts_validate.
