This series contains updates to i40e and igbvf drivers.
Marek removes a redundant assignment for i40e.
Stefan Assmann corrects reporting of VF link speed for i40e.
Karen revises a couple of error messages to warnings for igbvf as they
could be misinterpreted as issues when they are not.

If the underlying read operation failed we would end up writing stale
data to the supplied buffer. This would end up with the last
successfully read value repeating. Fix this by only writing the data
when we know the read was good. This will mean that failed values will
return 0xffff.

The MV88E6097 presents the serdes interrupts for ports 8 and 9 via the
Switch Global 2 registers. There is no additional layer of
enablinh/disabling the serdes interrupts like other mv88e6xxx switches.
Even though most of the serdes behaviour is the same as the MV88E6185
that chip does not provide interrupts for serdes events so unlike
earlier commits the functions added here are specific to the MV88E6097.

Implement serdes_power, serdes_get_lane and serdes_pcs_get_state ops for

ports and directly connected to other network interfaces or to SFPs

When a port is configured with 'managed = "in-band-status"' switch chips
like the 88E6390 need to propagate the SERDES link state to the MAC
because the link state is not correctly detected. This causes problems
on the 88E6185/88E6097 where the link partner won't see link state
changes because we're forcing the link.
To address this introduce a new device specific op port_sync_link() and
push the logic from mv88e6xxx_mac_link_up() into that. Provide an
implementation for the 88E6185 like devices which doesn't force the
link.

The rtl8211f supports downshift and before commit 5502b218e001
("net: phy: use phy_resolve_aneg_linkmode in genphy_read_status")
the read-back of register MII_CTRL1000 was used to detect the
negotiated link speed.
The code added in commit d445dff2df60 ("net: phy: realtek: read
actual speed to detect downshift") is working fine also for this
phy and it's trivial re-using it to restore the downshift
detection on rtl8211f.
Add the phy specific read_status() pointing to the existing
function rtlgen_read_status().

Now that all the PHY drivers have been migrated to directly implement
the generic .handle_interrupt() callback for a seamless support of
shared IRQs and all the .config_inter() implementations clear any
pending interrupts, we can safely remove the two callbacks.
With this patch, phylib has a proper support for shared IRQs (and not
just for multi-PHY devices. A PHY driver must implement both the
.handle_interrupt() and .config_intr() callbacks for the IRQs to be
actually used.

In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.
Also, add a comment describing the multiple step interrupt
acknoledgement process.

The driver's ISR sends a 'software interrupt' event to the probe()
thread using the following method:
- probe(): write 0 to flag, enable s/w interrupt
- probe(): poll on flag, relax using usleep_range()
- ISR : write 1 to flag
Replace with wake_up() / wait_event_timeout(). Besides being easier
to get right, this abstraction has better timing and memory
consistency properties.

Unresolved nexthops are currently written to the adjacency table with a

the 'DISCARD_ROUTER3' trap which can be enabled or disabled on demand,
but is always enabled in order to ensure the kernel can resolve the
unresolved neighbours.
This trap will be needed for blackhole nexthops support. Therefore, move
unresolved nexthops to explicitly program the adjacency entries with a

Up until now RIFs (router interfaces) were created on demand (e.g.,
when an IP address was added to a netdev). However, sometimes the device
needs to be provided with a RIF when one might not be available.
For example, adjacency entries that drop packets need to be programmed
with an egress RIF despite the RIF not being used to forward packets.
Create such a RIF during initialization so that it could be used later
on to support blackhole nexthops.

This driver uses a normal timer for TX coalescing, which means that the
with the default tx-usecs of 1000 microseconds the cleanups actually
happen 10 ms or more later with HZ=100. This leads to very low
througput with TCP when bridged to a slow link such as a 4G modem. Fix
this by using an hrtimer instead.
On my ARM platform with HZ=100 and the default TX coalescing settings
(tx-frames 25 tx-usecs 1000), with "tc qdisc add dev eth0 root netem
