The issue is that in the code above, set_bit is never reached

====================
net: Add address attribute to control metric of prefix route
For use cases such as VRR (Virtual Router Redundancy) interface managers
want efficient control over the order of prefix routes when multiple
interfaces have addresses with overlapping/duplicate subnets.
Currently, if two interfaces have addresses in the same subnet, the order
of the prefix route entries is determined by the order in which the
addresses are assigned or the links brought up. Any actions like cycling
an interface up and down changes that order. This set adds a new attribute
for addresses to allow a user to specify the metric of the prefix route
associated with an address giving interface managers better and more
efficient control of the order of prefix routes.
Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config
struct. The functions currently have a long list of arguments and adding
the metric just makes it worse. Because of the overall diff size in
moving the arguments to a struct, the change is done in stages to make
it easier to review starting with the bottom function and pushing the
struct up to callers in each successive patch.
Patch 4 introduces the new attribute.
Patches 5 and 6 add support for the new attribute to IPv4 and IPv6
addresses.
Patch 7 adds a set of test cases.
Patch 8 adds support to iproute2
Changes since RFC
- collapsed patches 1 and 3 into patch 2
- simplified stack variables in fib_modify_prefix_metric in patch 5

Add support for IFA_RT_PRIORITY to ipv6 addresses.
If the metric is changed on an existing address then the new route
is inserted before removing the old one. Since the metric is one
of the route keys, the prefix route can not be atomically replaced.

Move config parameters for adding an ipv6 address to a struct. struct
names stem from inet6_rtm_newaddr which is the modern handler for
adding an address.
Start the conversion to ifa6_config with ipv6_add_addr. This is an argument
move only; no functional change intended. Mapping of variable changes:
addr --> cfg->pfx
peer_addr --> cfg->peer_pfx
pfxlen --> cfg->plen
flags --> cfg->ifa_flags
scope, valid_lft, prefered_lft have the same names within cfg
(with corrected spelling).

mlxsw: use MRSR register for FW reset
Jiri says:
Introduce a MRSR register definition and use it to do FW reset instead
of existing mechanism using PCI BAR0 register.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

So far, the PCI BAR0 register is used for triggering FW reset. However,
that is a legacy attitude and it is recommended to use MRSR to perform
reset instead. So do that. Move the reset into init() function as
the cmd interface needs to be used. With that, IRQ initialization needs
to be moved as well. As a side effect, the reset move simplifies
the devlink reload flow.

There is an exception in command interface processing in case the MRSR
register is written to. The register triggers FW reset and during the
reset FW returns an error. So handle this by ignoring this error while
writing to MRSR register.

VLAN 1 is internally used for untagged traffic. Prevent creation of
explicit netdevice for that VLAN, because that currently isn't supported
and leads to the NULL pointer dereference cited below.
Fix by preventing creation of VLAN devices with VID of 1 over mlxsw
devices or LAG devices that involve mlxsw devices.

In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.
This is another attempt to tackle the issue. The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching. And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones. For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.
So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.
However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.
In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues. For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.

Jakub Kicinski says:
====================
nfp: abm: RED/MQ qdisc offload
This is second batch of advanced buffer management nfp driver
changes. This series adds the qdisc offload. Support for
a very simple subset of RED qdisc offload is added as needed
for DCTCP ECN marking (min and max thresholds set to the same
value).
The first two patches fix glitches introduced by the previous
series. We have to be careful about phys_port_name handling,
because VFs share the same code path, and some user space may
get confused by the names we chose.
Since unlike previous offloads we can report the queue backlog
both in bytes and packets we need to adjust how statistics are
added up in the core (patch 6).
There are some extra statistics we want to expose which don't
fit into TC stats, namely counts of packets which have been fast-
-forwarded without getting enqueued because there was no
contention and number of packets that were ever queued (sum of
all momentary backlogs). We expose those through ethtool stats
(patches 8 and 9).
Remaining 5 patches add MQ offload - to be able to set different
configurations on different queues. Representors are made multi-
-queue and we add offload support to MQ. MQ stats are added up
before calling ->dump qdiscs on the children, and therefore don't
include updated offload values. To avoid clearly incorrect stats
MQ is made to also request stats update from offloads. This way
we can correct the diff at the driver level.

will read the old values for its sums. Call into the drivers,
because of the additive nature of the stats drivers are aware
of how much "pending updates" they have to children of the MQ.
Since MQ reset its stats on every dump we can simply offset
the stats, predicting how stats of offloaded children will
change.

mq offload is trivial, we just need to let the device know
that the root qdisc is mq. Alternative approach would be
to export qdisc_lookup() and make drivers check the root
type themselves, but notification via ndo_setup_tc is more
in line with other qdiscs.
Note that mq doesn't hold any stats on it's own, it just
adds up stats of its children.

AFAICT struct gnet_stats_queue.qlen is not used in Qdiscs.
It may, however, be useful for offloads to report HW queue
length there. Add that value to the result of qdisc_qlen_sum().

ABM NIC FW has a cut-through mode where the PCIe queuing
is bypassed, thus working like our standard NIC FWs. Use this
mode by default and only enable queuing in switchdev mode where
users can configure it.

After recent change we started returning 0 from
ndo_get_phys_port_name for VFs. The name parameter for
ndo_get_phys_port_name is not initialized by the stack so
this can lead to a crash. We should have kept returning
-EOPNOTSUPP in the first place.

mlx5e-updates-2018-05-25
This series includes updates for mlx5e netdev driver.
1) Allowr flow based VF vport mirroring under sriov switchdev scheme,
added support for offloading the TC mirred mirror sub-action, from
Chris Mi.
=================
From: Or Gerlitz <ogerlitz@mellanox.com>
The user will typically set the actions order such that the mirror
port (mirror VF) sees packets as the original port (VF under
mirroring) sent them or as it will receive them. In the general case,
it means that packets are potentially sent to the mirror port before
or after some actions were applied on them.
To properly do that, we follow on the exact action order as set for
the flow and make sure this will also be the case when we program the
HW offload.
If all the actions should apply before forwarding to the mirror and dest port,
mirroring is just multicasting to the two vports. Otherwise, we split
the TC flow to two HW rules, where the 1st applies only the actions
needed up to the mirror (if there are such) and the 2nd the rest of
the actions plus the forwarding to the dest vport.
=================
2) Move to order-0 only allocations (using fragmented work queues) for all
work queues used by the driver, RX and TX descriptor rings
(RQs, SQs and Completion Queues (CQs)), from Tariq Toukan.
3) Avoid resetting netdevice statistics on netdevice
state changes, from Eran Ben Elisha.
