We were skipping the prepare phase which causes some problems with at
least a couple of drivers:
- mv88e6xxx chooses to skip programming VID = 0 with -EOPNOTSUPP in
the prepare phase, but we would still try to force this VID since we
would only call the commit phase and so we would get the driver to
return -EINVAL instead
- qca8k does not currently have a port_vlan_add() callback implemented,
yet we would try to call that unconditionally leading to a NPD
Fix both issues by conforming to the current model doing a
prepare/commit phase, this makes us consistent throughout the code and
assumptions.

sched: Patches from out-of-tree version of sch_cake
This series includes a couple of patches with updates from the out-of-tree
version of sch_cake. The first one is a fix to the fairness scheduling when
dual-mode fairness is enabled. The second patch is an additional feature flag

With more modes added the logic in cake_select_tin() was getting a bit
hairy, and it turns out we can actually simplify it quite a bit. This also
allows us to get rid of one of the two diffserv parsing functions, which
has the added benefit that already-zeroed DSCP fields won't get re-written.

Add flag 'FWMARK' to enable use of firewall connmarks as tin selector.
The connmark (skbuff->mark) needs to be in the range 1->tin_cnt ie.
for diffserv3 the mark needs to be 1->3.
Background
Typically CAKE uses DSCP as the basis for tin selection. DSCP values
are relatively easily changed as part of the egress path, usually with
iptables & the mangle table, ingress is more challenging. CAKE is often
used on the WAN interface of a residential gateway where passthrough of
DSCP from the ISP is either missing or set to unhelpful values thus use
of ingress DSCP values for tin selection isn't helpful in that
environment.
An approach to solving the ingress tin selection problem is to use
CAKE's understanding of tc filters. Naive tc filters could match on
source/destination port numbers and force tin selection that way, but
multiple filters don't scale particularly well as each filter must be
traversed whether it matches or not. e.g. a simple example to map 3
firewall marks to tins:
MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
tc filter add dev $DEV parent $MAJOR protocol all handle 0x01 fw action skbedit priority ${MAJOR}1
tc filter add dev $DEV parent $MAJOR protocol all handle 0x02 fw action skbedit priority ${MAJOR}2
tc filter add dev $DEV parent $MAJOR protocol all handle 0x03 fw action skbedit priority ${MAJOR}3
Another option is to use eBPF cls_act with tc filters e.g.
MAJOR=$( tc qdisc show dev $DEV | head -1 | awk '{print $3}' )
tc filter add dev $DEV parent $MAJOR bpf da obj my-bpf-fwmark-to-class.o
This has the disadvantages of a) needing someone to write & maintain
the bpf program, b) a bpf toolchain to compile it and c) needing to
hardcode the major number in the bpf program so it matches the cake
instance (or forcing the cake instance to a particular major number)
since the major number cannot be passed to the bpf program via tc
command line.
As already hinted at by the previous examples, it would be helpful
to associate tins with something that survives the Internet path and
ideally allows tin selection on both egress and ingress. Netfilter's
conntrack permits setting an identifying mark on a connection which
can also be restored to an ingress packet with tc action connmark e.g.
tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \
match u32 0 0 flowid 1:1 action connmark action mirred egress redirect dev ifb1
Since tc's connmark action has restored any connmark into skb->mark,
any of the previous solutions are based upon it and in one form or
another copy that mark to the skb->priority field where again CAKE
picks this up.
This change cuts out at least one of the (less intuitive &
non-scalable) middlemen and permit direct access to skb->mark.

CAKE host fairness does not work well with TCP flows in dual-srchost and
dual-dsthost setup. The reason is that ACKs generated by TCP flows are
classified as sparse flows, and affect flow isolation from other hosts. Fix
this by calculating host_load based only on the bulk flows a host
generates. In a hash collision the host_bulk_flow_count values must be
decremented on the old hosts and incremented on the new ones *if* the queue
is in the bulk set.

When macb device is suspended and system is powered down, the clocks
are removed and hence macb should be closed gracefully and restored
upon resume. This patch does the same by switching off the net device,
suspending phy and performing necessary cleanup of interrupts and BDs.
Upon resume, all these are reinitialized again.
Reset of macb device is done only when GEM is not a wake device.
Even when gem is a wake device, tx queues can be stopped and ptp device
can be closed (tsu clock will be disabled in pm_runtime_suspend) as
wake event detection has no dependency on this.

net: mvpp2: fixes and improvements
This series aims to improve the Marvell PPv2 driver and to fix various
issues we encountered while testing the ports in many different
configurations. The series is based on top of Russell PPv2 phylink
rework and improvement.
I'm not sending a v2 of the previous fixes series as half the patches
are not the same and lots of development happened in between.
While this series contains fixes, it's sent to net-next as it is based
on top of Russell patches that were merged into net-next. I'm also
aiming at net-next as the series reworks critical paths of the PPv2
driver, such as the reset handling of various blocks, to let more weeks
for users to tests and for possible fixes to be sent before it lands
into a stable kernel version.
The series is divided into three parts:
- Patches 1 to 3 are cosmetic changes, sent alongside the series, as I
saw these small issues while working on this.
- Patches 5 to 8 are fixing (or improving) individual issues that we
found while testing PPv2.1 and PPv2.2 ports while using various
interfaces.
Notable fixes are we support back RGMII interfaces (on both PPv2.1 and
PPv2.2), as their support was broken by previous patches. We also
reworked the RXQ computation as the RXQ assignment was not checking
the maximum number of RXQ available, and was broken for PPv2.1.
- As discussed in a previous fixes series, patches 9 to 15 rework the
way blocks are set in reset in the PPv2 engine (plus related changes).
There are four blocks we want to control the reset status: two MAC
(GMAC and XLG MAC) and two PCS (MPCS and XPCS). The XLG MAC is used
for 10G connexions and uses the MPCS or the XPCS depending on the mode
used (10GKR / XAUI / RXAUI) and the GMAC is used for the other modes.
The idea is to set all blocks in reset by default, and when not used,
and to de-assert the reset only when a block is used. There are four
cases to take in account:
1. Boot time: all four blocks should be put in reset, as we do not
know their initial state (configured by the firmware/bootloader).
2. Link up: only the blocks used by a given mode should be put out of
reset (eg. 10GKR uses the XLG MAC and the MPCS).
3. Mode reconfiguration: some ports may support mode reconfiguration,
and switching between the GMAC and the XLG MAC (or between the two
PCS). All blocks should be put in reset, and only the one used
should be put out of reset.
4. Link down: all four blocks are put in reset.

This patch adds calls in the stop() helper to ensure both MACs and
both PCS blocks are set in reset when the user manually sets a port
down. This is done so that we have the exact same block reset states at
boot time and when a port is set down.

This patch sets both the XPCS and MPCS blocks in reset when they aren't
used. This is done both at boot time and when reconfiguring a port mode.
The advantage now is that only the PCS used is set out of reset when the
port is configured (10GKR uses the MCPS while RXAUI uses the XPCS).

This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset
while a port is reconfigured. This is done so that we make sure a MAC is
in a reset state when not used, as only one of the two will be set out
of reset after the port is configured properly.

This patch reworks the way the XLG MAC is set in reset: the XLG MAC is
set in reset at probe time and taken out of this state only when used.
The idea is to move forward a situation where only the blocks used are
taken out of reset. This also has the effect to handle the GMAC and the
XLG MAC in a similar way (the GMAC already is set in reset at boot
time).

This patch force the XLG MAC link state in the phylink link_up() and
link_down() helpers when not using in-band auto-negotiation. This mimics
what's already done for the GMAC and follows what's advised in the
phylink documentation.

This patch improves the XLG configuration function, to only update the
XLG configuration register when a change is needed. This helps not
writing over and over the same XLG configuration each time phylink
request the MAC to be configured. This mimics the GMAC configuration
function.

This patch modifies the port_disable() helper to always disable both the
GMAC and the XLG MAC when called. At boot time we do not know of a port
was enabled in the firmware/bootloader, and if so what mode was used
(hence which of the two MACs was used).
This also help in implementing a logic where all blocks are disabled
when not used, and only enabled regarding the current mode used on a
given port.

The GMAC configuration helper modifies values in the auto-negotiation
register. Some of its values require the port to be forced down when
modifying their values. This patches fixes the check made on the bit to
be updated in this register, so that the port is forced down when
needed. This fix cases where some of those parameters were updated, but
not taken into account, such as when using RGMII interfaces.

The patch fixes the computation of RXQs being used by the PPv2 driver,
which is set depending on the PPv2 engine version and the queue mode
used. There are three cases:
- PPv2.1: 1 RXQ per CPU.
- PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU.
- PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs.
The PPv2 engine supports a maximum of 32 queues per port. This patch
adds a check so that we do not overstep this maximum.
It appeared the calculation was broken for PPv2.1 engines since
f8c6ba8424b0, as PPv2.1 ports ended up with a single RXQ while they
needed 4. This patch fixes it.
Fixes: f8c6ba8424b0 ("net: mvpp2: use only one rx queue per port per CPU")

The Phylink validate function is the Marvell PPv2 driver makes a check
on the GoP id. This is valid an has to be done when using PPv2.2 engines
but makes no sense when using PPv2.1. The check done when using an RGMII
interface makes sure the GoP id is not 0, but this breaks PPv2.1. Fixes
it.

This patch adds a check on the PPv2 version in-use not to reconfigure
the port mode when an interface is updated when using PPv2.1 as the
functions called are PPv2.2 specific.

We had a check in the mvpp2_mac_link_down() function (called by phylink)
to avoid disabling the port when link interrupts are used. It turned out
the interrupt can still be used with the port disabled. We can thus
remove this check.
