All of the code to support adaptive interrupt throttling is already in
the interrupt handler, it just needs to be enabled. Fill out the data
structures properly to make it happen. Single-flow traffic tests may
show slightly lower throughput, but interrupts per second will drop by
about 75%.

This patch increases minimum number of allocated VSIs, so as to resolve
failure adding VSI for VF when 64-VFs assigned to a PF. The driver
supports up to 128 VFs per device, users can decide to enable up to
64-VFs on a single PF, especially 2 X 40 devices. In that scenario, with
VMDq co-existence, there would be starvation of VSIs - with this patch,
supported features would have enough VSIs for configuration now.

In i40e_fdir_check_and_reenable(), the driver performs some checks to
determine whether it is safe to re-enable FD Sideband and FD ATR
support. The current check will only determine if there is available
space in the flow director table. However, this ignores the fact that
ATR should be disabled when there are TCP/IPv4 sideband rules in effect.
Add the missing check, and update the info message printed when
I40E_DEBUG_FD is enabled.

Some locations that disable ATR accidentally used the "full" disable by
disabling the flag in the standard flags field. This incorrectly forces
ATR off permanently instead of temporarily disabling it. In addition,
some code locations accidentally set the ATR flag enabled when they only
meant to clear the auto_disable_flags. This results in ignoring the
user's ethtool private flag settings.
Additionally, when disabling ATR via ethtool, we did not perform a flush
of the FD table. This results in the previously assigned ATR rules still
functioning which was not expected.
Cleanup all these areas so that automatic disable uses only the
auto_disable_flag. Fix the flush code so that we can trigger a flush
even when we've disabled ATR and SB support, as otherwise the flush
doesn't work. Fix ethtool setting to actually request a flush. Fix
NETIF_F_NTUPLE flag to only clear the auto_disable setting and not
enable the full feature.

Add ENCAP_CSUM offload negotiation flag. Currently VF assumes checksum
offload for encapsulated packets is supported by default. Going forward,
this feature needs to be negotiated with PF before advertising to the
stack. Hence, we need a flag to control it.
This is in regards to prepping up for VF base mode functionality support.

There exists a bug in which deleting a mac filter does not actually
occur. The driver reports that the filter has been deleted with no
error. The problem occurs because the wrong cmd_flag is passed to the
firmware when deleting the filter. The firmware reports an error back
to the driver but it is expressly ignored.
This fixes the bug by using the correct flag when deleting a filter.
Without this patch, deleted filters remain in firmware and function as
if they had not been deleted.

This patch fixes the problem where driver shows 100 Mbps as a supported speed,
and allows it to be configured for advertising on X722 devices. This patch
fixes the problem by not setting the 100 Mbps SGMII flag for X722 devices.
Without this patch, the user incorrectly thinks that 100 Mbps is supported
and hence might try to advertise it on X722 devices when it is actually not
a supported speed.

This patch fixes the possibility of a deadlock when bringing up
secondary CPUs.
The deadlock occurs because the set_cpu_online() is called before
synchronise_count_slave(). This can cause a deadlock if the boot CPU,
having scheduled another thread, attempts to send an IPI to the
secondary CPU, which it sees has been marked online. The secondary is
blocked in synchronise_count_slave() waiting for the boot CPU to enter
synchronise_count_master(), but the boot cpu is blocked in
smp_call_function_many() waiting for the secondary to respond to it's
IPI request.
Fix this by marking the CPU online in cpu_callin_map and synchronising
counters before declaring the CPU online and calculating the maps for
IPIs.

Implement RxRPC slow-start, which is similar to RFC 5681 for TCP. A
tracepoint is added to log the state of the congestion management algorithm
and the decisions it makes.
Notes:
(1) Since we send fixed-size DATA packets (apart from the final packet in
each phase), counters and calculations are in terms of packets rather
than bytes.
(2) The ACK packet carries the equivalent of TCP SACK.
(3) The FLIGHT_SIZE calculation in RFC 5681 doesn't seem particularly
suited to SACK of a small number of packets. It seems that, almost
inevitably, by the time three 'duplicate' ACKs have been seen, we have
narrowed the loss down to one or two missing packets, and the
FLIGHT_SIZE calculation ends up as 2.
(4) In rxrpc_resend(), if there was no data that apparently needed
retransmission, we transmit a PING ACK to ask the peer to tell us what
its Rx window state is.

If we've sent all the request data in a client call but haven't seen any
sign of the reply data yet, schedule an ACK to be sent to the server to
find out if the reply data got lost.
If the server hasn't yet hard-ACK'd the request data, we send a PING ACK to
demand a response to find out whether we need to retransmit.
If the server says it has received all of the data, we send an IDLE ACK to
tell the server that we haven't received anything in the receive phase as
yet.
To make this work, a non-immediate PING ACK must carry a delay. I've chosen
the same as the IDLE ACK for the moment.

When determining the resend timer value, we have a value in nsec but the
timer is in jiffies which may be a million or more times more coarse.
nsecs_to_jiffies() rounds down - which means that the resend timeout
expressed as jiffies is very likely earlier than the one expressed as
nanoseconds from which it was derived.
The problem is that rxrpc_resend() gets triggered by the timer, but can't
then find anything to resend yet. It sets the timer again - but gets
kicked off immediately again and again until the nanosecond-based expiry
time is reached and we actually retransmit.
Fix this by adding 1 to the jiffies-based resend_at value to counteract the
rounding and make sure that the timer happens after the nanosecond-based
expiry is passed.
Alternatives would be to adjust the timestamp on the packets to align
with the jiffie scale or to switch back to using jiffie-timestamps.

When faulting on some trap, the kernel currently reports in dmesg:
do_page_fault() command='perl' type=6 address=0xbe400403 in libcrypt-2.24.so[f9086000+9000]
vm_start = 0x00922000, vm_end = 0x00aed000
With this change the trap type additionally gets reported as human readable
string which makes it simpler to recognize the type of problem:
do_page_fault() command='perl' type=6 address=0xbe400403 in libcrypt-2.24.so[f9086000+9000]

This replaces the last uses of NF_HOOK_THRESH().
Followup patch will remove it and rename nf_hook_thresh.
The reason is that inet (non-bridge) netfilter no longer invokes the
hooks from hooks, so we do no longer need the thresh value to skip hooks
with a lower priority.
The bridge netfilter however may need to do this. br_nf_hook_thresh is a
wrapper that is supposed to do this, i.e. only call hooks with a
priority that exceeds NF_BR_PRI_BRNF.
It's used only in the recursion cases of br_netfilter. It invokes
nf_hook_slow while holding an rcu read-side critical section to make a
future cleanup simpler.

drms_uA_update() always returns failure when it cannot find regulator's
input voltage. But if hardware supports load configuration with
ops->set_load() and the input regulator isn't specified with valid reason
such as the input regulator is battery, not finding input voltage is
normal so such case should not return with an error.
Avoid such inadequate error return by checking input/output voltages
only when drms_uA_update() is about to configure load with enum based
ops->set_mode().
