The enetc scheduler for IEEE 802.1Qbv has 2 options (depending on
PTGCR[TG_DROP_DISABLE]) when we attempt to send an oversized packet
which will never fit in its allotted time slot for its traffic class:
either block the entire port due to head-of-line blocking, or drop the
packet and set a bit in the writeback format of the transmit buffer
descriptor, allowing other packets to be sent.
We obviously choose the second option in the driver, but we do not
detect the drop condition, so from the perspective of the network stack,
the packet is sent and no error counter is incremented.
This change checks the writeback of the TX BD when tc-taprio is enabled,
and increments a specific ethtool statistics counter and a generic
"tx_dropped" counter in ndo_get_stats64.

Future work in this driver would like to look at priv->active_offloads &
ENETC_F_QBV to determine whether a tc-taprio qdisc offload was
installed, but this does not produce the intended effect.
All the other flags in priv->active_offloads are managed dynamically,
except ENETC_F_QBV which is set statically based on the probed SI capability.
This change makes priv->active_offloads & ENETC_F_QBV really track the
presence of a tc-taprio schedule on the port.
Some existing users, like the enetc_sched_speed_set() call from
phylink_mac_link_up(), are best kept using the old logic: the tc-taprio
offload does not re-trigger another link mode resolve, so the scheduler
needs to be functional from the get go, as long as Qbv is supported at
all on the port. So to preserve functionality there, look at the static
station interface capability from pf->si->hw_features instead.

This driver was using the TX IRQ handler to perform all TX completion
tasks. Under heavy TX network load, this can cause significant irqs-off
latencies (found to be in the hundreds of microseconds using ftrace).
This can cause other issues, such as overrunning serial UART FIFOs when
using high baud rates with limited UART FIFO sizes.
Switch to using a NAPI poll handler to perform the TX completion work
to get this out of hard IRQ context and avoid the IRQ latency impact. A
separate NAPI instance is used for TX and RX to avoid checking the other
ring's state unnecessarily when doing the poll, and so that the NAPI
budget handling can work for both TX and RX packets.
A new per-queue tx_ptr_lock spinlock has been added to avoid using the
main device lock (with IRQs needing to be disabled) across the entire TX
mapping operation, and also to protect the TX queue pointers from
concurrent access between the TX start and TX poll operations.
The TX Used Bit Read interrupt (TXUBR) handling also needs to be moved into
the TX NAPI poll handler to maintain the proper order of operations. A flag
is used to notify the poll handler that a UBR condition needs to be
handled. The macb_tx_restart handler has had some locking added for global
register access, since this could now potentially happen concurrently on
different queues.

Previously the macb_poll method was checking the RSR register after
completing its RX receive work to see if additional packets had been
received since IRQs were disabled, since this controller does not
maintain the pending IRQ status across IRQ disable. It also had to
double-check the register after re-enabling IRQs to detect if packets
were received after the first check but before IRQs were enabled.
Using the RSR register for this purpose is problematic since it reflects
the global device state rather than the per-queue state, so if packets
are being received on multiple queues it may end up retriggering receive
on a queue where the packets did not actually arrive and not on the one
where they did arrive. This will also cause problems with an upcoming
change to use NAPI for the TX path where use of multiple queues is more
likely.
Add a macb_rx_pending function to check the RX ring to see if more
packets have arrived in the queue, and use that to check if NAPI should
be rescheduled rather than the RSR register. By doing this, we can just
ignore the global RSR register entirely, and thus save some extra device
register accesses at the same time.
This also makes the previous first check for pending packets rather
redundant, since it would be checking the RX ring state which was just
checked in the receive work function. Therefore we can get rid of it and
just check after enabling interrupts whether packets are already
pending.

The bug is here:
ret = i40e_add_macvlan_filter(hw, ch->seid, vdev->dev_addr, &aq_err);
The list iterator 'ch' will point to a bogus position containing
HEAD if the list is empty or no element is found. This case must
be checked before any use of the iterator, otherwise it will
lead to a invalid memory access.
To fix this bug, use a new variable 'iter' as the list iterator,
while use the origin variable 'ch' as a dedicated pointer to
point to the found element.

https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux into v5.19/vfio/next
Improve mlx5 live migration driver
From Yishai:
This series improves mlx5 live migration driver in few aspects as of
below.
Refactor to enable running migration commands in parallel over the PF
command interface.
To achieve that we exposed from mlx5_core an API to let the VF be
notified before that the PF command interface goes down/up. (e.g. PF
reload upon health recovery).
Once having the above functionality in place mlx5 vfio doesn't need any
more to obtain the global PF lock upon using the command interface but
can rely on the above mechanism to be in sync with the PF.
This can enable parallel VFs migration over the PF command interface
from kernel driver point of view.
In addition,
Moved to use the PF async command mode for the SAVE state command.
This enables returning earlier to user space upon issuing successfully
the command and improve latency by let things run in parallel.
Alex, as this series touches mlx5_core we may need to send this in a
pull request format to VFIO to avoid conflicts before acceptance.

In aq_ring_rx_clean(), if buff->is_eop is not set AND
buff->len < AQ_CFG_RX_HDR_SIZE, then hdr_len remains equal to
buff->len and skb_add_rx_frag(xxx, *0*, ...) is not called.
The loop following this code starts calling skb_add_rx_frag() starting
with i=1 and thus frag[0] is never initialized. Since i is initialized
to zero at the top of the primary loop, we can just reference and
post-increment i instead of hardcoding the 0 when calling
skb_add_rx_frag() the first time.

mlx5-updates-2022-05-09
1) Gavin Li, adds exit route from waiting for FW init on device boot and
increases FW init timeout on health recovery flow
2) Support 4 ports HCAs LAG mode
Mark Bloch Says:
================
This series adds to mlx5 drivers support for 4 ports HCAs.
Starting with ConnectX-7 HCAs with 4 ports are possible.
As most driver parts aren't affected by such configuration most driver
code is unchanged.
Specially the only affected areas are:
- Lag
- Devcom
- Merged E-Switch
- Single FDB E-Switch
Lag was chosen to be converted first. Creating hardware LAG when all 4
ports are added to the same bond device.
Devom, merge E-Switch and single FDB E-Switch, are marked as supporting
only 2 ports HCAs and future patches will add support for 4 ports HCAs.
In order to activate the hardware lag a user can execute the:
ip link add bond0 type bond
ip link set bond0 type bond miimon 100 mode 2
ip link set eth2 master bond0
ip link set eth3 master bond0
ip link set eth4 master bond0
ip link set eth5 master bond0
Where eth2, eth3, eth4 and eth5 are the PFs of the same HCA.

Currently, upon virtual interface creation, wfx_add_interface() stores
a reference to the corresponding struct ieee80211_vif in private data,
for later usage. This is not needed when using the container_of
construct. This construct already has all the info it needs to retrieve
the reference to the corresponding struct from the offset that is
already available, inherent in container_of(), between its type and
member inputs (struct ieee80211_vif and drv_priv, respectively).
Remove vif (which was previously storing the reference to the struct
ieee80211_vif) from the struct wfx_vif, define a function
wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with
the newly defined container_of construct.

The variables vht_mcs and he_mcs are being initialized in the
start of for-loops however they are re-assigned new values in
the loop and not used outside the loop. The initializations
are redundant and can be removed.
Cleans up clang scan warnings:
warning: Although the value stored to 'vht_mcs' is used in the
enclosing expression, the value is never actually read from
'vht_mcs' [deadcode.DeadStores]
warning: Although the value stored to 'he_mcs' is used in the
enclosing expression, the value is never actually read from
'he_mcs' [deadcode.DeadStores]

Ath11k allocates memory when firmware requests memory in QMI.
Coldboot calibration and firmware recovery uses firmware reload.
On firmware reload, firmware sends memory request again. If Ath11k
allocates memory on first firmware boot, reuse the available
memory. Also check if the segment type and size is same
on the next firmware boot. Reuse if segment type/size is
same as previous firmware boot else free the segment and
allocate the segment with size/type.
