When fw does not know the next hop for an IPv6 tunnel, it sends a request
to the driver.
Handle this request by doing a route lookup on the IPv6 address and
offloading the next hop to the fw neighbour table.
Similar functions already exist to handle IPv4 no neighbour requests. To
avoid confusion, append these functions with the _ipv4 tag. There is no
change in functionality with this.

The IPv4 set tunnel action allows the setting of tunnel metadata such as
the TTL and ToS values. The pre-tunnel action includes the destination IP
address and is used to calculate the next hop from from the neighbour
table.
Much of the IPv4 tunnel actions can be reused for IPv6 tunnels. Change the
names of associated functions and structs to remove the IPv4 identifier
and make minor modifcations to support IPv6 tunnel actions.
Ensure the pre-tunnel action contains the IPv6 address along with an
identifying flag when an IPv6 tunnel action is required.

Fw requires a list of IPv6 addresses that are used as tunnel endpoints to
enable correct decap of tunneled packets.
Store a list of IPv6 endpoints used in rules with a ref counter to track
how many times it is in use. Offload the entire list any time a new IPv6
address is added or when an address is removed (ref count is 0).

IPv6 tunnel matches are now supported by firmware. Modify the NFP driver
to compile these match rules. IPv6 matches are handled similar to IPv4
tunnels with the difference the address length. The type of tunnel is
indicated by the same bitmap that is used in IPv4 with an extra bit
signifying that the IPv6 variation should be used.
Only compile IPv6 tunnel matches when the fw features symbol indicated
that they are compatible with the currently loaded fw.

IPv4 UDP and GRE tunnel match rule compile helpers share functions for
compiling fields such as IP addresses. However, they handle fields such
tunnel IDs differently.
Create new helper functions for compiling GRE and UDP tunnel key data.
This is in preparation for supporting IPv6 tunnels where these new
functions can be reused.
This patch does not change functionality.

In kernel 5.1, the flow offload API was introduced along with a helper
function to extract the flow_rule from the TC offload struct. Each of the
match helper functions are passed the offload struct and extract the flow
rule to a local variable.
Simplify the code while also removing the extra compat and local variable
calls by extracting the rule once in the main match handler, and passing
a reference to the rule direct to each helper.
This patch does not change driver functionality.

Presently, at boot time, the comphys are enabled. For firmware
compatibility reasons, the comphy driver does not power down the
comphys at boot. Consequently, the ethernet comphys are left active
until the network interfaces are brought through an up/down cycle.
If the port is never used, the port wastes power needlessly. Arrange
for the ethernet comphys to be cycled by the mvpp2 driver as if the
interface went through an up/down cycle during driver probe, thereby
powering them down.
This saves:
270mW per 10G SFP+ port on the Macchiatobin Single Shot (eth0/eth1)
370mW per 10G PHY port on the Macchiatobin Double Shot (eth0/eth1)
160mW on the SFP port on either Macchiatobin flavour (eth3)

marvell_read_status_page_an() always reads the PHY status register, but
marvell_update_link() has already done this. Rather than wastefully
reading the register twice in quick succession, read it once in
marvell_read_status_page() and use the result for both.
This makes marvell_update_link() rather pointless, so move it into
marvell_read_status_page().

Move the initialisation of the link partner state earlier, inside
marvell_read_status_page(), so we don't have the same initialisation
scattered amongst the other files. This is in a similar place to
the genphy implementation, so would result in the same behaviour if
a PHY read error occurs.
This allows us to get rid of marvell_read_status_page_fixed(), which
became a pointless wrapper around genphy_read_status_fixed().

When we have pending packets we re-arm the TX timer with a magic value.
This changes the re-arm of the timer from 10us to the user-defined
coalesce value. As we support different speeds, having a magic value of
10us can be either too short or to large depending on the speed so we
let user configure it. The default value of the timer is 1ms but it can
be reconfigured by ethtool.

...as the comment above the function states.
The switch to Initialising at the start of the function is somewhat bogus
as the toolstack will have set that initial state anyway. To behave
correctly, a backend should switch to InitWait once it has set up all
xenstore values that may be required by a initialising frontend. This
patch calls backend_switch_state() to make the transition at the
appropriate point.
NOTE: backend_switch_state() ignores errors from xenbus_switch_state()
and so this patch removes an error path from netback_probe(). This
means a failure to change state at this stage (in the absence of
other failures) will leave the device instantiated. This is highly
unlikley to happen as a failure to change state would indicate a
failure to write to xenstore, and that will trigger other error
paths. Also, a 'stuck' device can still be cleaned up using 'unbind'
in any case.

Currently, the hardware TID index is assumed to start from index 0.
However, with the following changeset,
commit c21939998802 ("cxgb4: add support for high priority filters")
hardware TID index can start after the high priority region, which
has introduced a regression resulting in connection failures for
ULDs.
So, fix all related code to properly recalculate the TID start index
based on whether high priority filters are enabled or not.

Fix up the mvpp2 validate implementation to adopt the same behaviour as
mvneta:
- only allow the link modes that the specified PHY interface mode
supports with the exception of 1000base-X and 2500base-X.
- use the basex helper to deal with SFP modules that can be switched
between 1000base-X vs 2500base-X.
This gives consistent behaviour between mvneta and mvpp2.
This commit depends on "net: phylink: extend clause 45 PHY validation
workaround" so is not marked for backporting to stable kernels.

Commit e45d1f5288b8 ("net: phylink: support Clause 45 PHYs on SFP+
modules") added a workaround to support clause 45 PHYs which
dynamically switch their interface mode on SFP+ modules. This was
implemented by validating the PHYs supported/advertising using
PHY_INTERFACE_MODE_NA, rather than the specific interface mode that
we attached the PHY with.
However, we already have a situation where phylink is used to connect
a Marvell 88X3310 PHY which also behaves in exactly the same way, but
which seemingly doesn't need this. The reason seems to be that the
mvpp2 driver sets a whole bunch of link modes for
PHY_INTERFACE_MODE_10GKR down to 10Mb/s, despite 10GBASE-R not actually
supporting anything but 10Gb/s speeds.
When testing with drivers that (correctly) take the mvneta approach,
where the validate() method only returns what can be supported /
advertised for the specified link mode, we find that Clause 45 PHYs do
not behave as we expect: their advertisement is restricted to what
the current link will support, rather than what the PHY supports
through its dynamic switching.
Extend this workaround to all such cases; if we have a Clause 45 PHY
attaching via any means, except in USXGMII, XAUI and RXAUI which are
all unable to support this dynamic switching or have other solutions
to it, then we need to validate using PHY_INTERFACE_MODE_NA.
This should allow mvpp2 to switch to a more conformant validate()
implementation.

While testing ethtool with the Methode DM7052 module, it was noticed
that attempting to set the advertising mask results in the mask being
truncated to the support offered by the currently chosen PHY interface
mode.
When a PHY dynamically changes the PHY interface mode, limiting the
advertising mask in this way is not correct - if the PHY happened to
negotiate 10GBASE-T, and selected 10GBASE-R as the host interface, we
don't want to restrict the advertisement to just 10GBASE-* modes.
Rework setting the advertisement to take account of this; do not pass
the requested advertisement through phylink_validate(), but rely on
the advertisement restriction (supported mask) set when the PHY was
initially setup.
