Real number of Transmit queues are incremented when user enables HTB
class and vice versa. Depending on SKB priority driver returns transmit
queue (Txq). Transmit queues and Send queues are one-to-one mapped.
In few scenarios, Driver is returning transmit queue value which is
greater than real number of transmit queue and Stack detects this as
error and overwrites transmit queue value.
For example
user has added two classes and real number of queues are incremented
accordingly
- tc class add dev eth1 parent 1: classid 1:1 htb
rate 100Mbit ceil 100Mbit prio 1 quantum 1024
- tc class add dev eth1 parent 1: classid 1:2 htb
rate 100Mbit ceil 200Mbit prio 7 quantum 1024
now if user deletes the class with id 1:1, driver decrements the real
number of queues
- tc class del dev eth1 classid 1:1
But for the class with id 1:2, driver is returning transmit queue
value which is higher than real number of transmit queue leading
to below error
eth1 selects TX queue x, but real number of TX queues is x
This patch solves the problem by assigning deleted class transmit
queue/send queue to active class.

Erhard reports netpoll warnings from sungem:

WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c
gem_poll_controller() disables interrupts, which may sleep.
We can't sleep in netpoll, it has interrupts disabled completely.
Strangely, gem_poll_controller() doesn't even poll the completions,
and instead acts as if an interrupt has fired so it just schedules
NAPI and exits. None of this has been necessary for years, since
netpoll invokes NAPI directly.

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

According to hardware limitation, for device support modify
VLAN filter state but not support bypass port VLAN filter,
it should always disable the port VLAN filter. but the driver
enables port VLAN filter when initializing, if there is no
VLAN(except VLAN 0) id added, the driver will disable it
in service task. In most time, it works fine. But there is
a time window before the service task shceduled and net device
being registered. So if user adds VLAN at this time, the driver
will not update the VLAN filter state, and the port VLAN filter
remains enabled.
To fix the problem, if support modify VLAN filter state but not
support bypass port VLAN filter, set the port vlan filter to "off".

During successful probe, igc logs this:
[ 5.133667] igc 0000:01:00.0 (unnamed net_device) (uninitialized): PHC added
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The reason is that igc_ptp_init() is called very early, even before
register_netdev() has been called. So the netdev_info() call works
on a partially uninitialized netdev.
Fix this by calling igc_ptp_init() after register_netdev(), right
after the media autosense check, just as in igb. Add a comment,
just as in igb.

This driver currently doesn't support any control flags.
Use flow_rule_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.

Currently the ipq806x dwmac driver is almost always used attached to the
CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii".
Some device came up with a special configuration where the PHY is
directly attached to the GMAC port and in those case phy-mode needs to
be set to "rgmii-id" to make the PHY correctly work and receive packets.
Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"
(or variants) mode is set, the mode is rejected and probe fails.
Add support also for these phy-modes to correctly setup PHYs that requires
delay applied to tx/rx.

XSk infra's been using its own DMA sync shortcut to try avoiding
redundant function calls. Now that there is a generic one, remove
the custom implementation and rely on the generic helpers.
xsk_buff_dma_sync_for_cpu() doesn't need the second argument anymore,
remove it.

Simon reported that ndo_change_mtu() methods were never
updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted
in commit 501a90c94510 ("inet: protect against too small
mtu values.")
We read dev->mtu without holding RTNL in many places,
with READ_ONCE() annotations.
It is time to take care of ndo_change_mtu() methods
to use corresponding WRITE_ONCE()

In qede_flow_spec_to_rule(), when calling
qede_parse_actions() then the return code
was only used for a non-zero check, and then
-EINVAL was returned.
qede_parse_actions() can currently fail with:
* -EINVAL
* -EOPNOTSUPP
Commit 319a1d19471e ("flow_offload: check for
basic action hw stats type") broke the implicit
assumption that it could only fail with -EINVAL,
by changing it to return -EOPNOTSUPP, when hardware
stats are requested.
However AFAICT it's not possible to trigger
qede_parse_actions() to return -EOPNOTSUPP, when
called from qede_flow_spec_to_rule(), as hardware
stats can't be requested by ethtool_rx_flow_rule_create().
This patch changes qede_flow_spec_to_rule() to use
the actual return code from qede_parse_actions(),
so it's no longer assumed that all errors are -EINVAL.

According to GCC, the constriction of irq_name in otx2_open()
may, theoretically, be truncated.
This patch takes the approach of treating such a situation as an error
which it detects by making use of the return value of snprintf, which is
the total number of bytes, excluding the trailing '\0', that would have
been written.
Based on the approach taken to a similar problem in
commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()")
Flagged by gcc-13 W=1 builds as:
.../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]
1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name,
| ^
.../otx2_pf.c:1933:17: note: 'snprintf' output between 8 and 33 bytes into a destination of size 32

Refactor struct ice_vsi_cfg_params to be embedded into struct ice_vsi.
Prior to that the members of the struct were scattered around ice_vsi,
and were copy-pasted for purposes of reinit.
Now we have struct handy, and it is easier to have something sticky
in the flags field.

The PTP_CMD_CTL is a self clearing register which controls the PTP clock
values. In the current implementation driver waits for a duration of 20
sec in case of HW failure to clear the PTP_CMD_CTL register bit. This
timeout of 20 sec is very long to recognize a HW failure, as it is
typically cleared in one clock(<16ns). Hence reducing the timeout to 1 sec
would be sufficient to conclude if there is any HW failure observed. The
usleep_range will sleep somewhere between 1 msec to 20 msec for each
iteration. By setting the PTP_CMD_CTL_TIMEOUT_CNT to 50 the max timeout
is extended to 1 sec.

Every tx and rx ring has its own queue-page-list (QPL) that serves as
the bounce buffer. Previously we were allocating QPLs for all queues
before the queues themselves were allocated and later associating a QPL
with a queue. This is avoidable complexity: it is much more natural for
each queue to allocate and free its own QPL.
Moreover, the advent of new queue-manipulating ndo hooks make it hard to
keep things as is: we would need to transfer a QPL from an old queue to
a new queue, and that is unpleasant.
