We rename some functions and variables, to make their purpose clearer.

- tipc_group::congested -> tipc_group::small_win. Members in this list
  are not necessarily (and typically) congested. Instead, they may
  *potentially* be subject to congestion because their send window is
  less than ADV_IDLE, and therefore need to be checked during message
  transmission.

- tipc_group_is_receiver() -> tipc_group_is_sender(). This socket will
  accept messages coming from members fulfilling this condition, i.e.,
  they are senders from this member's viewpoint.

- tipc_group_is_enabled() -> tipc_group_is_receiver(). Members
  fulfilling this condition will accept messages sent from the current
  socket, i.e., they are receivers from its viewpoint.

There are no functional changes in this commit.

On multi-threaded processes, one common architecture is to have
one (or a small number of) threads polling sockets, and a
considerably larger pool of threads reading form and writing to the
sockets. When we set RPS core on tcp_poll() or udp_poll() we essentially
steer all packets of all the polled FDs to one (or small number of)
cores, creaing a bottleneck and/or RPS misprediction.

Another common architecture is to shard FDs among threads pinned
to cores. In such a setting, setting RPS core in tcp_poll() and
udp_poll() is redundant because the RFS core is correctly
set in recvmsg and sendmsg.

l2tp: remove configurable offset parameters

This patch series removes all code to support a configurable offset in
transmitted l2tp packets. Code to handle this is incomplete and buggy
and has been this way for years. If anyone tried to configure an
offset, it would be ignored for L2TPv2 tunnels, or for L2TPv3 tunnels,
could result in L2TPv3 packets being transmitted which are not
compliant with L2TPv3 RFC3931. This patch series removes the support
for configurable offsets.

No known userspace l2tp daemon configures an offset. However,
iproute2's "ip l2tp" command has an offset parameter and if set, the
value is passed to the kernel. This is the most likely use case where
offsets might be configured, e.g.

   ip l2tp add tunnel local 1.1.1.1 remote 1.1.1.2 tunnel_id 1 \
       peer_tunnel_id 2 encap ip
   ip l2tp add session name l2tp0 tunnel_id 1 session_id 1 \
       peer_session_id 2 offset 8

The above would result in packets being transmitted to 1.1.1.2 with 8
bytes padding between the L2TPv3 header and the payload. The peer
would need to be configured with the same offset value. However, the
packets are not compliant with the L2TPv3 RFC, hence I think it's
unlikely that offset is being used. With this patch series applied,
the offset would not be configured. The peer would need to be modified to
remove its offset setting too.

iproute2 should be modified to remove or ignore the ip l2tp offset
parameter.

This issue was discovered when reviewing a patch series from
lorenzo.bianconi@redhat.com which adds another netlink attribute to
configure the expected offset in received L2TPv3 packets. This change
is reverted by this series because offsets do not exist in L2TPv3
packets. These commits are:

  commit f15bc54e ("l2tp: add peer_offset parameter")
  commit 820da535 ("l2tp: fix missing print session offset info")

In more detail:

The L2TPv2 protocol supports a variable offset from the L2TPv2 header
to the payload to give the sender implementation some flexibility for
data alignment when adding L2TP headers on to payloads. The offset
value is indicated by an optional field in the L2TP header.  Our L2TP
implementation already detects the presence of the optional offset in
received packets and skips those bytes when parsing packets. All
transmitted L2TPv2 packets are always transmitted with no offset.

L2TPv3 has no optional offset field in the L2TPv3 packet
header. Instead, L2TPv3 defines optional fields in a "Layer-2 Specific
Sublayer". At the time when the original L2TP code was written, there
was talk at IETF of offset being implemented in a new Layer-2 Specific
Sublayer. A L2TP_ATTR_OFFSET netlink attribute was added so that this
offset could be configured and the intention was to allow it to be
also used to set the tx offset for L2TPv2. However, no L2TPv3 offset
was ever specified and the L2TP_ATTR_OFFSET parameter was forgotten
about.

Setting L2TP_ATTR_OFFSET results in L2TPv3 packets being transmitted
with the specified number of bytes padding between L2TPv3 header and
payload. This is not compliant with L2TPv3 RFC3931. So this change
removes the configurable offset altogether while retaining
L2TP_ATTR_OFFSET in the API for backwards compatibility. If
L2TP_ATTR_OFFSET is given, its value is now silently ignored.

nfp: flower: repr link state

Dirk says:

This series provides two updates towards the link state of reprs in
the flower nfp app.

Patch #1 improves the way link state is reported for reprs. Instead of
starting with an assumed 'UP' state, always assume the link state is
'DOWN' and then modify this only on events received from firmware.

Patch #2 adds a new nfp_app hook, repr_preclean. This callback is
executed before reprs are removed from the app context and is executed
per repr.

Patch #3 implements the new REIFY control message, used to indicate
when reprs are created and destroyed. Firmware uses these messages
to prevent communication about any particular port when the driver
doesn't know about the repr yet or anymore.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The PORT_REIFY message indicates whether reprs have been created or
when they are about to be destroyed. This is necessary so firmware
can know which state the driver is in, e.g. the firmware will not send
any control messages related to ports when the reprs are destroyed.

This prevents nuisance warning messages printed whenever the firmware
sends updates for non-existent reprs.

Resolve races in phy accessors

This series resolves races with various accesses to PHY registers.
The first five patches are necessary before we add phylink support
to mvneta, the remaining three are merely cleanups for unobserved
races, and hence are less critical.

There are two possible classes of races that can occur: where we
write to a page register that changes the meaning of a group of
other registers, and where we read-modify-write a register.

Resolve these races by performing the accesses under the mdio bus
lock, ensuring that no other user can access the bus while the
series of atomic operations are being performed.

These patches have been posted before, and have been modified
along the lines of previous feedback:

- The third patch was originally reviewed by Florian, but as I've
  added __phy_modify() to it, I've removed that attributation.
- Included generic page-based accessors as suggested last time
  around.
- Since we have the unlocked __phy_modify() in this patch series,
  it is sensible to include the changes for this to marvell.c -
  these accessors have to change anyway to avoid deadlocks on the
  mdio bus lock.

I haven't been able to test the at803x.c changes yet beyond compile
testing - although I do have systems with an ar8035 PHY.  However,
they should be straight forward to review.

This is targetted for net-next because the races have not been
found in existing drivers, but have been observed with phylink
integrated into mvneta - that's not to say that the races do not
exist today, they are just unobserved (probably through lack of
rigorous enough testing.)  The race provoking condition is detailed
in patch 5.

For paged accesses to be truely safe, we need to hold the bus lock to
prevent anyone else gaining access to the registers while we modify
them.

The phydev->lock mutex does not do this: userspace via the MII ioctl
can still sneak in and read or write any register while we are on a
different page, and the suspend/resume methods can be called by a
thread different to the thread polling the phy status.

Races have been observed with mvneta on SolidRun Clearfog with phylink,
particularly between the phylib worker reading the PHYs status, and
the thread resuming mvneta, calling phy_start() which then calls
through to m88e1121_config_aneg_rgmii_delays(), which tries to
read-modify-write the MSCR register:

	CPU0			CPU1
	marvell_read_status_page()
	marvell_set_page(phydev, MII_MARVELL_FIBER_PAGE)
	...
				m88e1121_config_aneg_rgmii_delays()
				set_page(MII_MARVELL_MSCR_PAGE)
				phy_read(phydev, MII_88E1121_PHY_MSCR_REG)
	marvell_set_page(phydev, MII_MARVELL_COPPER_PAGE);
	...
				phy_write(phydev, MII_88E1121_PHY_MSCR_REG)

The result of this is we end up writing the copper page register 21,
which causes the copper PHY to be disabled, and the link partner sees
the link immediately go down.

Solve this by taking the bus lock instead of the PHY lock, thereby
preventing other accesses to the PHY while we are accessing other PHY
pages.

Convert mvneta to phylink

This series converts mvneta to use phylink, which is necessary to
support the SFP cages on SolidRun's Clearfog platform.  This series just
converts mvneta without adding the DT parts - having discussed with
Andrew, we believe we're too close to the merge window to submit that
patch.

I've split the "net: mvneta: convert to phylink" patch up to make it
easier to review, and in doing so, spotted some minor corner cases that
needed to be fixed along the way.

This series depends on the previously merged phylink patches in netdev,
along with the recently reviewed 7 patch series "Resolve races in phy
accessors" without which, the race described in patch 5 of that series
is very evident when triggering a dummy hibernate cycle.

This series also illustrates how to convert mvpp2 to phylink.

mvneta is the only user of the fixed_phy_update_state() API, and this
becomes redundant with the conversion.

It would be good to get this series not only reviewed, but also
independently tested to ensure that I haven't missed anything - I only
have the Clearfog platform to test on, and that doesn't support all the
different interface modes that mvneta supports.

A particularly interesting side effect of this series is that DSA
switches no longer need the "CPU" port and DSA facing MAC ethernet
instance to be marked as a fixed link anymore with mvneta - we can use
1000BaseX mode, and the DSA to CPU link will use the 802.3z negotiation
to determine the link properties without needing the link parameters to
be explicitly stated in DT - that is a subject of a future patch.
