The `dma::Device` trait is to be implemented by bus device

Currently, the ath12k driver supports only the native Wi-Fi
frame format. In this mode, the ieee80211_tx_status() function
works correctly to report transmission status to mac80211, as
it retrieves station information using sta_info_get_by_addrs().
However, this method is not applicable for Ethernet-converted
packets, since sta_info_get_by_addrs() cannot extract station
information from such formats.
Retrieve station information using ath12k_peer_find_by_id() to
support all frame formats, including native Wi-Fi, raw, and Ethernet.
Report transmission status using ieee80211_tx_status_ext(), and
include rate information as part of the datapath TX status report.

/proc/cgroups lists only v1 controllers by default, however, this is
only enforced since the commit af000ce852 ("cgroup: Do not report
unavailable v1 controllers in /proc/cgroups") and there is software in
the wild that uses content of /proc/cgroups to decide on availability of
v2 (sic) controllers.
Add a boottime param that can bring back the previous behavior for
setups where the check in the software cannot be changed and it causes
e.g. unintended OOMs.
Also, this patch takes out cgrp_v1_visible from cgroup1_subsys_absent()
guard since it's only important to check which hierarchy (v1 vs v2) the
subsys is attached to. This has no effect on the printed message but
the code is cleaner since cgrp_v1_visible is really about mounted
hierarchies, not the content of /proc/cgroups.

Currently, in the transmit (TX) direction, EAPOL, QoS NULL,
and multicast frames are sent in native Wi-Fi (802.11) format.
However, when the virtual interface is configured in Ethernet
mode, transmission fails for packets enqueued in native Wi-fi format.
To address this issue, the firmware should be instructed to
treat these packets as RAW type packets, ensuring proper
handling even when the interface operates in Ethernet mode.

When a remote device sends a completion event to the host, it contains a
pointer to the consumed TRE. The host uses this pointer to process all of
the TREs between it and the host's local copy of the ring's read pointer.
This works when processing completion for chained transactions, but can
lead to nasty results if the device sends an event for a single-element
transaction with a read pointer that is multiple elements ahead of the
host's read pointer.
For instance, if the host accesses an event ring while the device is
updating it, the pointer inside of the event might still point to an old
TRE. If the host uses the channel's xfer_cb() to directly free the buffer
pointed to by the TRE, the buffer will be double-freed.
This behavior was observed on an ep that used upstream EP stack without
'commit 6f18d174b7 ("bus: mhi: ep: Update read pointer only after buffer
is written")'. Where the device updated the events ring pointer before
updating the event contents, so it left a window where the host was able to
access the stale data the event pointed to, before the device had the
chance to update them. The usual pattern was that the host received an
event pointing to a TRE that is not immediately after the last processed
one, so it got treated as if it was a chained transaction, processing all
of the TREs in between the two read pointers.
This commit aims to harden the host by ensuring transactions where the
event points to a TRE that isn't local_rp + 1 are chained.

The issue seems to be with the incorrect DMA address/size used for
transferring the firmware image over BHI. So fix it by converting the DMA
address and size of the BHI vector table to little endian format before
sending them to the device.

In the original design, it is assumed local and peer eswitches have the
same number of vfs. However, in new firmware, local and peer eswitches
can have different number of vfs configured by mlxconfig. In such
configuration, it is incorrect to derive the number of vfs from the
local device's eswitch.
Fix this by updating the peer miss rules add and delete functions to use
the peer device's eswitch and vf count instead of the local device's
information, ensuring correct behavior regardless of vf configuration
differences.

The TCP header fields seq and ack_seq are 32-bit values in network
byte order as (__be32). these fields were earlier printed using
ntohs(), which converts only 16-bit values and produces incorrect
results for 32-bit fields. This patch is changeing the conversion
to ntohl(), ensuring correct interpretation of these sequence numbers.
Notably, the format specifier is updated from %d to %u to reflect the
unsigned nature of these fields.
improves the accuracy of debug log messages for TCP sequence and
acknowledgment numbers during TX timeouts.

====================
net: maintain netif vs dev prefix semantics
Commit cc34acd577 ("docs: net: document new locking reality")
introduced netif_ vs dev_ function semantics: the former expects locked
netdev, the latter takes care of the locking. We don't strictly
follow this semantics on either side, but there are more dev_xxx handlers
now that don't fit. Rename them to netif_xxx where appropriate. We care only
about driver-visible APIs, don't touch stack-internal routines.
The rest seem to be ok:
* dev_xdp_prog_count - mostly called by sw drivers (bonding), should not matter
* dev_get_by_xxx - too many to reasonably cleanup, already have different flavors
* dev_fetch_sw_netstats - don't need instance lock
* dev_get_tstats64 - never called directly, only as an ndo callback
* dev_pick_tx_zero - never called directly, only as an ndo callback
* dev_add_pack / dev_remove_pack - called early enough (in module init) to not matter
* dev_get_iflink - mostly called by sw drivers, should not matter
* dev_fill_forward_path - ditto
* dev_getbyhwaddr_rcu - ditto
* dev_getbyhwaddr - ditto
* dev_getfirstbyhwtype - ditto
* dev_valid_name - ditto
* __dev_forward_skb dev_forward_skb dev_queue_xmit_nit - established helpers, no netif vs dev distinction

netif_close_many is used only by vlan/dsa and one mtk driver, so move it into
NETDEV_INTERNAL namespace.

Note that one dev_set_threaded call still remains in mt76 for debugfs file.
