During stress test with attaching and detaching VF from KVM and
simultaneously changing VFs spoofcheck and trust there was a
call trace in ice_reset_vf that VF's VSI is null.

Remove WARN_ON() from check if VSI is null in ice_reset_vf.
Add "VF is already removed\n" in dev_dbg().
This WARN_ON() is unnecessary and causes call trace, despite that
call trace, driver still works. There is no need for this warn
because this piece of code is responsible for disabling VF's Tx/Rx
queues when VF is disabled, but when VF is already removed there
is no need to do reset or disable queues.

In commit b03d519d3460 ("ice: store VF pointer instead of VF ID")
WARN_ON checks were added to validate the vsi->vf pointer and
catch programming errors. However, one check to vsi->vf was missed.
This caused a call trace when resetting VFs.
Fix ice_vsi_rebuild by encompassing VF pointer in WARN_ON check.

Currently, tls_device_down synchronizes with tls_device_resync_rx using
RCU, however, the pointer to netdev is stored using WRITE_ONCE and
loaded using READ_ONCE.
Although such approach is technically correct (rcu_dereference is
essentially a READ_ONCE, and rcu_assign_pointer uses WRITE_ONCE to store
NULL), using special RCU helpers for pointers is more valid, as it
includes additional checks and might change the implementation
transparently to the callers.
Mark the netdev pointer as __rcu and use the correct RCU helpers to
access it. For non-concurrent access pass the right conditions that
guarantee safe access (locks taken, refcount value). Also use the
correct helper in mlx5e, where even READ_ONCE was missing.
The transition to RCU exposes existing issues, fixed by this commit:
1. bond_tls_device_xmit could read netdev twice, and it could become
NULL the second time, after the NULL check passed.
2. Drivers shouldn't stop processing the last packet if tls_device_down
just set netdev to NULL, before tls_dev_del was called. This prevents a
possible packet drop when transitioning to the fallback software mode.

According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.

trigered by wrong bytes_compl") and potentially introduced by commit
b38c83dd0866 ("bgmac: simplify tx ring index handling").
If there is an RX interrupt between setting ring->end
and netdev_sent_queue() we can hit the BUG_ON as bgmac_dma_tx_free()
can miscalculate the queue size while called from bgmac_poll().
The machine which triggered the BUG runs a v4.14 RT kernel - but the issue
seems present in mainline too.

If tsnep_tx_map() fails, then tsnep_tx_unmap() shall start at the write
index like tsnep_tx_map(). This is different to the normal operation.
Thus, add an additional parameter to tsnep_tx_unmap() to enable start at
different positions for successful TX and failed TX.

Avoid the PHY library call unnecessarily into the suspend/resume functions by

exactly what mdio_bus_phy_resume() does by calling phy_init_hw() plus
phy_resume().

For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.
There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.

The port flag isn't set to `NFP_PORT_CHANGED` when using
`ethtool -m DEVNAME` before, so the port state (e.g. interface)
cannot be updated. Therefore, it caused that `ethtool -m DEVNAME`
sometimes cannot read the correct information.
E.g. `ethtool -m DEVNAME` cannot work when load driver before plug
in optical module, as the port interface is still NONE without port
update.
Now update the port state before sending info to NIC to ensure that
port interface is correct (latest state).

PTP messages like SYNC, FOLLOW_UP, DELAY_REQ are of size 58 bytes.
Using a minimum packet length as 64 makes NIX to pad 6 bytes of
zeroes while transmission. This is causing latest ptp4l application to
emit errors since length in PTP header and received packet are not same.
Padding upto 3 bytes is fine but more than that makes ptp4l to assume
the pad bytes as a TLV. Hence reduce the size to 60 from 64.

1GbE Intel Wired LAN Driver Updates 2022-07-28
Jacob Keller says:
Convert all of the Intel drivers with PTP support to the newer .adjfine
implementation which uses scaled parts per million.
This improves the precision of the frequency adjustments by taking advantage
of the full scaled parts per million input coming from user space.
In addition, all implementations are converted to using the
mul_u64_u64_div_u64 function which better handles the intermediate value.
This function supports architecture specific instructions where possible to
avoid loss of precision if the normal 64-bit multiplication would overflow.
Of note, the i40e implementation is now able to avoid loss of precision on
slower link speeds by taking advantage of this to multiply by the link speed
factor first. This results in a significantly more precise adjustment by
allowing the calculation to impact the lower bits.
This also gets us a step closer to being able to remove the .adjfreq
entirely by removing its use from many drivers.
I plan to follow this up with a series to update the drivers from other
vendors and drop the .adjfreq implementation entirely.

Representors do not want to be subject to the PF's Ethernet address
filters, since traffic from VFs will typically have a destination
either elsewhere on the link segment or on an overlay network.
So, create a dynamic m-port with promiscuous and all-multicast
filters, and set it as the egress port of representor default rules.
Since the m-port is an alias of the calling PF's own m-port, traffic
will still be delivered to the PF's RXQs, but it will be subject to
the VNRX filter rules installed on the dynamic m-port (specified by
the v-port ID field of the filter spec).

Default rules are low-priority switching rules which the hardware uses
in the absence of higher-priority rules. Each representor requires a
corresponding rule matching traffic from its representee VF and
delivering to the PF (where a check on INGRESS_MPORT in
__ef100_rx_packet() will direct it to the representor). No rule is
required in the reverse direction, because representor TX uses a TX
override descriptor to bypass the MAE and deliver directly to the VF.
Since inserting any rule into the MAE disables the firmware's own
default rules, also insert a pair of rules to connect the PF to the
physical network port and vice-versa.

If not, for now drop them and warn. A subsequent patch will look up
the source m-port to try and find a representor to deliver them to.

Traffic delivered to the (MAE admin) PF could be from either the wire
or a VF. The INGRESS_MPORT field of the RX prefix distinguishes these;
base_mport is the value this field will have for traffic from the wire
(which should be delivered to the PF's netdevice, not a representor).

Representor RX uses a NAPI context driven by a 'fake interrupt': when
the parent PF receives a packet destined for the representor, it adds
it to an SKB list (efv->rx_list), and schedules NAPI if the 'fake
interrupt' is primed. The NAPI poll then pulls packets off this list
and feeds them to the stack with netif_receive_skb_list().
This scheme allows us to decouple representor RX from the parent PF's
RX fast-path.
This patch implements the 'top half', which builds an SKB, copies data
into it from the RX buffer (which can then be released), adds it to
the queue and fires the 'fake interrupt' if necessary.

This patch adds the 'bottom half' napi->poll routine for representor RX.
See the next patch (with the top half) for an explanation of the 'fake
interrupt' scheme used to drive this NAPI context.
