mt76 core uses ffs() to find the next free bit. This works well for 32 bit
architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so
allocation fails on 64 bit architectures.
Additionally, the wcid mask array was too small in cases where the array
was not a multiple of BITS_PER_LONG.
Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP
for the size, just in case we ever bump it to a value that's not a multiple
of 32.

This patch adds a field to the tls rx offload context which enables
drivers to force a send_resync call.

This field can be used by drivers to request a resync at the next
possible tls record. It is beneficial for hardware that provides the
resync sequence number asynchronously. In such cases, the packet that
triggered the resync does not contain the information required for a
resync. Instead, the driver requests resync for all the following
TLS record until the asynchronous notification with the resync request
TCP sequence arrives.

A following series for mlx5e ConnectX-6DX TLS RX offload support will
use this mechanism.

net_sched: reduce the number of qdisc resets

This patchset aims to reduce the number of qdisc resets during
qdisc tear down. Patch 1~3 are preparation for their following
patches, especially patch 2 and patch 3 add a few tracepoints
so that we can observe the whole lifetime of qdisc's. Patch 4
and patch 5 are the ones do the actual work. Please find more
details in each patch description.

Vaclav Zindulka tested this patchset and his large ruleset with
over 13k qdiscs defined got from 22s to 520ms.

Resetting old qdisc on dev_queue->qdisc_sleeping in
dev_qdisc_reset() is redundant, because this qdisc,
even if not same with dev_queue->qdisc, is reset via
qdisc_put() right after calling dev_graft_qdisc() when
hitting refcnt 0.

This is very easy to observe with qdisc_reset() tracepoint
and stack traces.

Except for sch_mq and sch_mqprio, each dev queue points to the
same root qdisc, so when we reset the dev queues with
netdev_for_each_tx_queue() we end up resetting the same instance
of the root qdisc for multiple times.

Avoid this by checking the __QDISC_STATE_DEACTIVATED bit in
each iteration, so for sch_mq/sch_mqprio, we still reset all
of them like before, for the rest, we only reset it once.

qdisc_destroy() calls ops->reset() and cleans up qdisc->gso_skb
and qdisc->skb_bad_txq, these are nearly same with qdisc_reset(),
so just call it directly, and cosolidate the code for the next
patch.

tcp: tcp_v4_err() cleanups

This series is a followup of patch 23917494 ("tcp: tcp_v4_err() icmp
skb is named icmp_skb").

Move the RFC 6069 code into a helper, and rename icmp_skb to standard
skb name so that tcp_v4_err() and tcp_v6_err() are using consistent names.

This essentially reverts 4d1a2d9e ("Revert Backoff [v3]:
Rename skb to icmp_skb in tcp_v4_err()")

Now we have tcp_ld_RTO_revert() helper, we can use the usual
name for sk_buff parameter, so that tcp_v4_err() and
tcp_v6_err() use similar names.

RFC 6069 logic has been implemented for IPv4 only so far,
right in the middle of tcp_v4_err() and was error prone.

Move this code to one helper, to make tcp_v4_err() more
readable and to eventually expand RFC 6069 to IPv6 in
the future.

Also perform sock_owned_by_user() check a bit sooner.

net: mscc: allow forwarding ioctl operations to attached PHYs

These two patches allow forwarding ioctl to the PHY MII implementation,
and support is added for offloading timestamping operations to
compatible attached PHYs.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds support for offloading timestamping operations not only
to the Ocelot switch (as already supported) but to compatible PHYs.
When both the PHY and the Ocelot switch support timestamping operations,
the PHY implementation is chosen as the timestamp will happen closer to
the medium.

Allow ioctl to be implemented by the PHY, when a PHY is attached to the

The ocelot core library is written with the idea in mind that the VLAN
table is populated by the bridge. Otherwise, not even a sane default
pvid is provided: in standalone mode, the default pvid is 0, and the
core expects the bridge layer to change it to 1.

So without this patch, the VLAN table is completely empty at the end of
the commands below, and traffic is broken as a result:

ip link add dev br0 type bridge vlan_filtering 0 && ip link set dev br0 up
for eth in $(ls /sys/bus/pci/devices/0000\:00\:00.5/net/); do
	ip link set dev $eth master br0
	ip link set dev $eth up
done
ip link set dev br0 type bridge vlan_filtering 1
