So far we don't re-configure WOL-related register bits when waking up
from hibernation. I'm not aware of any problem reports, but better
play safe and call __rtl8169_set_wol() in the resume() path too.
To achieve this move calling __rtl8169_set_wol() to
rtl8169_net_resume() and rename the function to rtl8169_runtime_resume().

====================
net: phy: icplus: cleanups and new features
Cleanup the PHY drivers for IPplus devices and add PHY counters and MDIX
support for the IP101A/G.
Patch 5 adds a model detection based on the behavior of the PHY.
Unfortunately, the IP101A shares the PHY ID with the IP101G. But the latter
provides more features. Try to detect the newer model by accessing the page
selection register. If it is writeable, it is assumed, that it is a IP101G.
With this detection in place, we can now access registers >= 16 in a
correct way on the IP101G; that is by first selecting the correct page.
This might previouly worked, because no one ever set another active page
before booting linux.
The last two patches add the new features.

The IP101G provides three counters: RX packets, CRC errors and symbol
errors. The error counters can be configured to clear automatically on
read. Unfortunately, this isn't true for the RX packet counter. Because
of this and because the RX packet counter is more likely to overflow,
than the error counters implement only support for the error counters.

Registers >= 16 are paged. Be sure to set the page. It seems this was
working for now, because the default is correct for the registers used
in the driver at the moment. But this will also assume, nobody will
change the page select register before linux is started. The page select
register is _not_ reset with a soft reset of the PHY.
To ease the function reuse between the non-paged register space of the
IP101A and the IP101G, add noop read_page()/write_page() callbacks so
the IP101G functions can also be used for the IP101A.

Unfortunately, the IP101A and IP101G share the same PHY identifier.
While most of the functions are somewhat backwards compatible, there is
for example the APS_EN bit on the IP101A but on the IP101G this bit
reserved. Also, the IP101G has many more functionalities.
Deduce the model by accessing the page select register which - according
to the datasheet - is not available on the IP101A. If this register is
writable, assume we have an IP101G.
Split the combined IP101A/G driver into two separate drivers.

Add support for offloading of HSR/PRP (IEC 62439-3) tag insertion
tag removal, duplicate generation and forwarding.
For HSR, insertion involves the switch adding a 6 byte HSR header after
the 14 byte Ethernet header. For PRP it adds a 6 byte trailer.
Tag removal involves automatically stripping the HSR/PRP header/trailer
in the switch. This is possible when the switch also performs auto
deduplication using the HSR/PRP header/trailer (making it no longer
required).
Forwarding involves automatically forwarding between redundant ports in
an HSR. This is crucial because delay is accumulated as a frame passes
through each node in the ring.
Duplication involves the switch automatically sending a single frame
from the CPU port to both redundant ports. This is required because the
inserted HSR/PRP header/trailer must contain the same sequence number
on the frames sent out both redundant ports.
Export is_hsr_master so DSA can tell them apart from other devices in
dsa_slave_changeupper.

For a switch to offload insertion of HSR/PRP tags, frames must not be
sent to the CPU facing switch port with a tag. Generate supervision frames
(eth type ETH_P_PRP) without HSR v1 (ETH_P_HSR)/PRP tag and rely on
create_tagged_frame which inserts it later. This will allow skipping the
tag insertion for all outgoing frames in the future which is required for
HSR v1/PRP tag insertions to be offloaded.
HSR v0 supervision frames always contain tag information so insertion of
the tag can't be offloaded. IEC 62439-3 Ed.2.0 (HSR v1) specifically
notes that this was changed since v0 to allow offloading.

Even when implementing RFC 6056 3.3.4 (Algorithm 4: Double-Hash
Port Selection Algorithm), a patient attacker could still be able
to collect enough state from an otherwise idle host.
Idea of this patch is to inject some noise, in the
cases __inet_hash_connect() found a candidate in the first
attempt.
This noise should not significantly reduce the collision
avoidance, and should be zero if connection table
is already well used.
Note that this is not implementing RFC 6056 3.3.5
because we think Algorithm 5 could hurt typical
workloads.

RFC 6056 (Recommendations for Transport-Protocol Port Randomization)
provides good summary of why source selection needs extra care.
David Dworken reminded us that linux implements Algorithm 3
as described in RFC 6056 3.3.3
Quoting David :
In the context of the web, this creates an interesting info leak where
websites can count how many TCP connections a user's computer is
establishing over time. For example, this allows a website to count
exactly how many subresources a third party website loaded.
This also allows:
- Distinguishing between different users behind a VPN based on
distinct source port ranges.
- Tracking users over time across multiple networks.
- Covert communication channels between different browsers/browser
profiles running on the same computer
- Tracking what applications are running on a computer based on
the pattern of how fast source ports are getting incremented.
Section 3.3.4 describes an enhancement, that reduces
attackers ability to use the basic information currently
stored into the shared 'u32 hint'.
This change also decreases collision rate when
multiple applications need to connect() to
different destinations.

In commit c9dca822c729 ("net-loopback: set lo dev initial state to UP"),
linux started automatically bringing up the loopback device of a newly
created namespace. However, an existing user script might reasonably have
the following stanza when creating a new namespace -- and in fact at least
tools/testing/selftests/net/fib_nexthops.sh in Linux's very own testsuite
does:
# set -e
# ip netns add foo
# ip -netns foo addr add 127.0.0.1/8 dev lo
# ip -netns foo link set lo up
# set +e
This will now fail, because the kernel reasonably rejects "ip addr add" of
a duplicate address. The described change of behavior therefore constitutes
a breakage. Revert it.

At the moment, PORT_MII is reported in the ethtool ops. This is odd
because it is an interface between the MAC and the PHY and no external
port. Some network card drivers will overwrite the port to twisted pair
or fiber, though. Even worse, the MDI/MDIX setting is only used by
ethtool if the port is twisted pair.
Set the port to PORT_TP by default because most PHY drivers are copper
ones. If there is fibre support and it is enabled, the PHY driver will
set it to PORT_FIBRE.
This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE;
except for the genphy fallback driver.

Flow director for IPv6 is not supported.
1) Implementation of support for IPv6 flow director.
2) Added handlers for addition of TCP6, UDP6, SCTP6, IPv6.
3) Refactored legacy code to make it more generic.
4) Added packet templates for TCP6, UDP6, SCTP6, IPv6.
5) Added handling of IPv6 source and destination address for flow director.
6) Improved argument passing for source and destination portin TCP6, UDP6
and SCTP6.
7) Added handling of ethtool -n for IPv6, TCP6,UDP6, SCTP6.
8) Used correct bit flag regarding FLEXOFF field of flow director data
descriptor.
Without this patch, there would be no support for flow director on IPv6,
TCP6, UDP6, SCTP6.
Tested based on x710 datasheet by using:
ethtool -N enp133s0f0 flow-type tcp4 src-port 13 dst-port 37 user-def 0x44142 action 1
ethtool -N enp133s0f0 flow-type tcp6 src-port 13 dst-port 40 user-def 0x44142 action 2
ethtool -N enp133s0f0 flow-type udp4 src-port 20 dst-port 40 user-def 0x44142 action 3
ethtool -N enp133s0f0 flow-type udp6 src-port 25 dst-port 40 user-def 0x44142 action 4
ethtool -N enp133s0f0 flow-type sctp4 src-port 55 dst-port 65 user-def 0x44142 action 5
ethtool -N enp133s0f0 flow-type sctp6 src-port 60 dst-port 40 user-def 0x44142 action 6
ethtool -N enp133s0f0 flow-type ip4 src-ip 1.1.1.1 dst-ip 1.1.1.4 user-def 0x44142 action 7
ethtool -N enp133s0f0 flow-type ip6 src-ip fe80::3efd:feff:fe6f:bbbb dst-ip fe80::3efd:feff:fe6f:aaaa user-def 0x44142 action 8
Then send traffic from client which matches the criteria provided to ethtool.
Observe that packets are redirected to user set queues with ethtool -S <interface>

The changes to make rxrpc create the udp socket missed a bit to add the
Kconfig dependency on the udp tunnel code to do this.
Fix this by adding making AF_RXRPC select NET_UDP_TUNNEL.
Fixes: 1a9b86c9fd95 ("rxrpc: use udp tunnel APIs instead of open code in rxrpc_open_socket")

====================
ethtool support for fec and link configuration
This series of patches add support for forward error correction(fec) and
physical link configuration. Patches 1&2 adds necessary mbox handlers for fec
mode configuration request and to fetch stats. Patch 3 registers driver
callbacks for fec mode configuration and display. Patch 4&5 adds support of mbox
handlers for configuring link parameters like speed/duplex and autoneg etc.
Patche 6&7 registers driver callbacks for physical link configuration.
Change-log:
v2:
- Fixed review comments
- Corrected indentation issues
- Return -ENOMEM incase of mbox allocation failure
- added validation for input fecparams bitmask values
- added more comments
V3:
- Removed inline functions
- Make use of ethtool helpers APIs to display supported
advertised modes
- corrected indentation issues
- code changes such that return early in case of failure
to aid branch prediction
v4:
- Corrected indentation issues
- Use FEC_OFF if user requests for FEC_AUTO mode
- Do not clear fec stats in case of user changes
fec mode
- dont hide fec stats depending on interface mode
selection

This patch adds support to fetch fec stats from PHY. The stats are
put in the shared data struct fwdata. A PHY driver indicates
that it has FEC stats by setting the flag fwdata.phy.misc.has_fec_stats
Besides CGX_CMD_GET_PHY_FEC_STATS, also add CGX_CMD_PRBS and
CGX_CMD_DISPLAY_EYE to enum cgx_cmd_id so that Linux's enum list is in sync
with firmware's enum list.
