E830 is the 200G NIC family which uses the ice driver.
Add specific E830 registers. Embed macros to use proper register based on
(hw)->mac_type & name those macros to [ORIGINAL]_BY_MAC(hw). Registers
only available on one of the macs will need to be explicitly referred to
as E800_NAME instead of just NAME. PTP is not yet supported.

The recent firmware interface change has added 2 counters in struct
rx_port_stats_ext. This caused 2 stray ethtool counters to be
displayed.
Since new counters are added from time to time, fix it so that the
ethtool logic will only display up to the maximum known counters.
These 2 counters are not used by production firmware yet.

In iavf_down, we're skipping the scheduling of certain operations if
the driver is being removed. However, the IAVF_FLAG_AQ_DISABLE_QUEUES
request must not be skipped in this case, because iavf_close waits
for the transition to the __IAVF_DOWN state, which happens in
iavf_virtchnl_completion after the queues are released.
Without this fix, "rmmod iavf" takes half a second per interface that's
up and prints the "Device resources not yet released" warning.

Currently, the logic to return an ath12k_sta pointer, given a
ieee80211_sta pointer, uses typecasting throughout the driver. In
general, conversion functions are preferable to typecasting since
using a conversion function allows the compiler to validate the types
of both the input and output parameters.
ath12k already defines a conversion function ath12k_vif_to_arvif() for
a similar conversion. So introduce ath12k_sta_to_arsta() for this use
case, and convert all of the existing typecasting to use this
function.

Firmware IE containers can dynamically provide various information
what firmware supports. Also it can embed more than one image so
updating firmware is easy, user just needs to update one file in
/lib/firmware/.
The firmware API 2 or higher will use the IE container format, the
current API 1 will not use the new format but it still is supported
for some time. Firmware API 2 files are named as firmware-2.bin
(which contains both amss.bin and m3.bin images) and API 1 files are
amss.bin and m3.bin.
Currently ath11k PCI driver provides firmware binary (amss.bin) path to
MHI driver, MHI driver reads firmware from filesystem and boots it. Add
provision to read firmware files from ath11k driver and provide the amss.bin
firmware data and size to MHI using a pointer.
Currently enum ath11k_fw_features is empty, the patches adding features will
add the flags.
With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB

Simple refactoring to make it easier to add firmware-2.bin support in the
following patch.
Earlier ath11k_qmi_m3_load() supported changing m3.bin contents while ath11k is
running. But that's not going to actually work, m3.bin is supposed to be the
same during the lifetime of ath11k, for example we don't support changing the
firmware capabilities on the fly. Due to this ath11k requests m3.bin firmware
file first and only then checks m3_mem->vaddr, so we are basically requesting
the firmware file even if it's not needed. Reverse the code so that m3_mem
buffer is checked first, and only if it doesn't exist, then m3.bin is requested
from user space.
Checking for m3_mem->size is redundant when m3_mem->vaddr is NULL, we would
not be able to use the buffer in that case. So remove the check for size.
Simplify the exit handling and use 'goto out'.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect new_entry->dbf_name to be NUL-terminated based on its use with
strcmp():
| if (strcmp(entry->dbf_name, name) == 0) {
Moreover, NUL-padding is not required as new_entry is kzalloc'd just
before this assignment:
| new_entry = kzalloc(sizeof(struct qeth_dbf_entry), GFP_KERNEL);
... rendering any future NUL-byte assignments (like the ones strncpy()
does) redundant.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

strings:
CTCM_DBF_TEXT_(SETUP, CTC_DBF_INFO, "%s(%s) %s", CTCM_FUNTAIL,

Moreover, NUL-padding is not required as it is _only_ used in this one
instance with a format string.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
We can also drop the +1 from chid's declaration as we no longer need to
be cautious about leaving a spot for a NUL-byte. Let's use the more
idiomatic strscpy usage of (dest, src, sizeof(dest)) as this more
closely ties the destination buffer to the length.

This work adds a new, minimal BPF-programmable device called "netkit"
(former PoC code-name "meta") we recently presented at LSF/MM/BPF. The
core idea is that BPF programs are executed within the drivers xmit routine
and therefore e.g. in case of containers/Pods moving BPF processing closer
to the source.
One of the goals was that in case of Pod egress traffic, this allows to
move BPF programs from hostns tcx ingress into the device itself, providing
earlier drop or forward mechanisms, for example, if the BPF program
determines that the skb must be sent out of the node, then a redirect to
the physical device can take place directly without going through per-CPU
backlog queue. This helps to shift processing for such traffic from softirq
to process context, leading to better scheduling decisions/performance (see
measurements in the slides).
In this initial version, the netkit device ships as a pair, but we plan to
extend this further so it can also operate in single device mode. The pair
comes with a primary and a peer device. Only the primary device, typically
residing in hostns, can manage BPF programs for itself and its peer. The
peer device is designated for containers/Pods and cannot attach/detach
BPF programs. Upon the device creation, the user can set the default policy
to 'pass' or 'drop' for the case when no BPF program is attached.
Additionally, the device can be operated in L3 (default) or L2 mode. The
management of BPF programs is done via bpf_mprog, so that multi-attach is
supported right from the beginning with similar API and dependency controls
as tcx. For details on the latter see commit 053c8e1f235d ("bpf: Add generic
attach/detach/query API for multi-progs"). tc BPF compatibility is provided,
so that existing programs can be easily migrated.
Going forward, we plan to use netkit devices in Cilium as the main device
type for connecting Pods. They will be operated in L3 mode in order to
simplify a Pod's neighbor management and the peer will operate in default
drop mode, so that no traffic is leaving between the time when a Pod is
brought up by the CNI plugin and programs attached by the agent.
Additionally, the programs we attach via tcx on the physical devices are
using bpf_redirect_peer() for inbound traffic into netkit device, hence the
latter is also supporting the ndo_get_peer_dev callback. Similarly, we use
bpf_redirect_neigh() for the way out, pushing from netkit peer to phys device
directly. Also, BIG TCP is supported on netkit device. For the follow-up
work in single device mode, we plan to convert Cilium's cilium_host/_net
devices into a single one.
An extensive test suite for checking device operations and the BPF program
and link management API comes as BPF selftests in this series.

Currently there is a device tree entry called "local-mac-address"
which can be filled by the bootloader or manually set.This is
useful when the user does not want to use the MAC address
programmed into the SoC.
Currently, the davinci_emac reads the MAC from the DT, copies
it from pdata->mac_addr to priv->mac_addr, then blindly overwrites
it by reading from registers in the SoC, and falls back to a
random MAC if it's still not valid. This completely ignores any
MAC address in the device tree.
In order to use the local-mac-address, check to see if the contents
of priv->mac_addr are valid before falling back to reading from the
SoC when the MAC address is not valid.

Currently all RX frames are timestamped which results in a performance
penalty when timestamping is not needed. The default is now being
changed to not timestamp any Rx frames (HWTSTAMP_FILTER_NONE), but
support has been added to allow changing the desired RX timestamping
mode (HWTSTAMP_FILTER_ALL - which was the previous setting and
HWTSTAMP_FILTER_PTP_V2_EVENT are now supported) using
SIOCSHWTSTAMP. All settings were tested using the hwstamp_ctl application.
It is also noted that ptp4l, when started, preconfigures the device to
timestamp using HWTSTAMP_FILTER_PTP_V2_EVENT, so this driver continues
to work properly "out of the box".
