cycle time for a particular schedule is calculated only when it is first
installed. So, it makes sense to just calculate it once right after the
'cycle_time' parameter has been parsed and store it in cycle_time.

Currently, etf expects a socket with SO_TXTIME option set for each packet
it encounters. So, it will drop all other packets. But, in the future
commits we are planning to add functionality where tstamp value will be set
by another qdisc. Also, some packets which are generated from within the
kernel (e.g. ICMP packets) do not have any socket associated with them.
So, this commit adds support for skip_sock_check. When this option is set,
etf will skip checking for a socket and other associated options for all
skbs.

If a packet which is utilizing the launchtime feature (via SO_TXTIME socket
option) also requests the hardware transmit timestamp, the hardware
timestamp is not delivered to the userspace. This is because the value in
skb->tstamp is mistaken as the software timestamp.
Applications, like ptp4l, request a hardware timestamp by setting the
SOF_TIMESTAMPING_TX_HARDWARE socket option. Whenever a new timestamp is
detected by the driver (this work is done in igb_ptp_tx_work() which calls
igb_ptp_tx_hwtstamps() in igb_ptp.c[1]), it will queue the timestamp in the
ERR_QUEUE for the userspace to read. When the userspace is ready, it will
issue a recvmsg() call to collect this timestamp. The problem is in this
recvmsg() call. If the skb->tstamp is not cleared out, it will be
interpreted as a software timestamp and the hardware tx timestamp will not
be successfully sent to the userspace. Look at skb_is_swtx_tstamp() and the
callee function __sock_recv_timestamp() in net/socket.c for more details.

Track recursive calls in TC act_mirred
These patches aim to prevent act_mirred causing stack overflow events from
recursively calling packet xmit or receive functions. Such events can
occur with poor TC configuration that causes packets to travel in loops
within the system.
Florian Westphal advises that a recursion crash and packets looping are
separate issues and should be treated as such. David Miller futher points
out that pcpu counters cannot track the precise skb context required to
detect loops. Hence these patches are not aimed at detecting packet loops,
rather, preventing stack flows arising from such loops.
====================

TC hooks allow the application of filters and actions to packets at both
ingress and egress of the network stack. It is possible, with poor
configuration, that this can produce loops whereby an ingress hook calls
a mirred egress action that has an egress hook that redirects back to
the first ingress etc. The TC core classifier protects against loops when
doing reclassifies but there is no protection against a packet looping
between multiple hooks and recursively calling act_mirred. This can lead
to stack overflow panics.
Add a per CPU counter to act_mirred that is incremented for each recursive
call of the action function when processing a packet. If a limit is passed
then the packet is dropped and CPU counter reset.
Note that this patch does not protect against loops in TC datapaths. Its
aim is to prevent stack overflow kernel panics that can be a consequence
of such loops.

The TC_ACT_REINSERT return type was added as an in-kernel only option to
allow a packet ingress or egress redirect. This is used to avoid
unnecessary skb clones in situations where they are not required. If a TC
hook returns this code then the packet is 'reinserted' and no skb consume
is carried out as no clone took place.
This return type is only used in act_mirred. Rather than have the reinsert
called from the main datapath, call it directly in act_mirred. Instead of
returning TC_ACT_REINSERT, change the type to the new TC_ACT_CONSUMED
which tells the caller that the packet has been stolen by another process
and that no consume call is required.
Moving all redirect calls to the act_mirred code is in preparation for
tracking recursion created by act_mirred.

Tools such as vpnc try to flush routes when run inside network
namespaces by writing 1 into /proc/sys/net/ipv4/route/flush. This
currently does not work because flush is not enabled in non-initial

Since routes are per network namespace it is safe to enable
/proc/sys/net/ipv4/route/flush in there.

PHYLINK being designed with PHYs in mind that can change MII protocol,
for correct operation it is necessary to ensure that the PHY interface
mode stays the same (otherwise clear the supported bit mask, as
required).
Because this is just a hypothetical situation for now, we don't bother
to check whether we could actually support the new PHY interface mode.
Actually we could modify the xMII table, reset the switch and send an
updated static configuration, but adding that would just be dead code.

It has been pointed out that PHYLINK can call mac_config only to update
the phy_interface_type and without knowing what the AN results are.
Experimentally, when this was observed to happen, state->link was also
unset, and therefore was used as a proxy to ignore this call. However it
is also suggested that state->link is undefined for this callback and
should not be relied upon.
So let the previously-dead codepath for SPEED_UNKNOWN be called, and
update the comment to make sure the MAC's behavior is sane.

The new route handling in ip_mc_finish_output() from 'net' overlapped
with the new support for returning congestion notifications from BPF
programs.
In order to handle this I had to take the dev_loopback_xmit() calls
out of the switch statement.
The aquantia driver conflicts were simple overlapping changes.

nfp: extend flower capabilities for GRE tunnel offload
Pieter says:
This set extends the flower match and action components to offload
GRE decapsulation with classification and encapsulation actions. The
first 3 patches are refactor and cleanup patches for improving
readability and reusability. Patch 4 and 5 implement GRE decap and
encap functionality respectively.

Add new GRE encapsulation support, which allows offload of filters
using tunnel_key set action in combination with actions that egress
to GRE type ports.

Extend the existing tunnel matching support to include GRE decap
classification. Specifically matching existing tunnel fields for
NVGRE (GRE with protocol field set to TEB).

Previously tunnel related functions in action offload only applied
to UDP tunnels. Rename these functions in preparation for new
tunnel types.

Refactor the key layer calculation function, in particular the tunnel
key layer calculation by introducing helper functions. This is done
in preparation for supporting GRE tunnel offloads.

net: dsa: microchip: Further regmap cleanups
This patchset cleans up KSZ9477 switch driver by replacing various
ad-hoc polling implementations and register RMW with regmap functions.
Each polling function is replaced separately to make it easier to review
and possibly bisect, but maybe the patches can be squashed.

Regmap provides read-modify-write function to update bitfields in
registers. Replace ad-hoc read-modify-write with regmap_update_bits()
where applicable.
