The variable mib_cnt is assigned with TOTAL_SWITCH_COUNTER_NUM. This
value can also be derived from the array size of mib_names. This patch
uses this calculated value instead, removes the extra define and uses
mib_cnt everywhere possible instead of the static define
TOTAL_SWITCH_COUNTER_NUM. Keeping it in a separate variable instead of
using ARRAY_SIZE everywhere instead makes the driver more flexible for
future use of devices with different amount of counters.

The extra define SWITCH_COUNTER_NUM is a copy of the KSZ8795_COUNTER_NUM
define. This patch initializes reg_mib_cnt with KSZ8795_COUNTER_NUM,
makes use of reg_mib_cnt everywhere instead and removes the extra

Jon Hunter reported observing a build bug in the IPA driver:
https://lore.kernel.org/netdev/5b5d9d40-94d5-5dad-b861-fd9bef8260e2@nvidia.com
The problem is that the QMB0 max read value set for IPA v4.5 (16) is
too large to fit in the 4-bit field.
The actual value we want is 0, which requests that the hardware use
the maximum it is capable of.

Stanislav Fomichev says:
====================
This might be useful for the listener sockets to pre-populate
some options. Since those helpers require locked sockets,
I'm changing bind hooks to lock/unlock the sockets. This
should not cause any performance overhead because at this
point there shouldn't be any socket lock contention and the
locking/unlocking should be cheap.
Also, as part of the series, I convert test_sock_addr bpf
assembly into C (and preserve the narrow load tests) to
make it easier to extend with th bpf_setsockopt later on.

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"I'm sad to say that we've got an unusually large arm64 fixes pull for
rc7 which addresses numerous significant instrumentation issues with
our entry code.
Without these patches, lockdep is hopelessly unreliable in some
configurations [1,2] and syzkaller is therefore not a lot of use
because it's so noisy.
Although much of this has always been broken, it appears to have been
exposed more readily by other changes such as 044d0d6de9 ("lockdep:
Only trace IRQ edges") and general lockdep improvements around IRQ
tracing and NMIs.
Fixing this properly required moving much of the instrumentation hooks
from our entry assembly into C, which Mark has been working on for the
last few weeks. We're not quite ready to move to the recently added
generic functions yet, but the code here has been deliberately written
to mimic that closely so we can look at cleaning things up once we
have a bit more breathing room.
Having said all that, the second version of these patches was posted
last week and I pushed it into our CI (kernelci and cki) along with a
commit which forced on PROVE_LOCKING, NOHZ_FULL and
CONTEXT_TRACKING_FORCE. The result? We found a real bug in the
md/raid10 code [3].
Oh, and there's also a really silly typo patch that's unrelated.
Summary:
- Fix numerous issues with instrumentation and exception entry
- Fix hideous typo in unused register field definition"

WLAN firmware will count is the AP still leaked packet after power save
handshake was done or not to enable WLAN slot extend mechanism.
The extend WLAN slot mechanism will extend the WLAN slot after power save
handshake, 5 ms per times, maximum is 5 times to received the leaked packet
to avoid the rate lower down.
And if the transmission was already locked at CCK rate.
The extended WLAN slot can also increase the opportunity that we can

kernel BUG at net/core/skbuff.c:109!
Call Trace:
skb_push+0x10/0x10
ip6gre_header+0x47/0x1b0
neigh_connected_output+0xae/0xf0
ip6gre tunnel provides its own header_ops->create, and sets it
conditionally when initializing the tunnel in NBMA mode. When
header_ops->create is used, dev->hard_header_len should reflect the
length of the header created. Otherwise, when not used,
dev->needed_headroom should be used.

The NO_160 flag specifies if the device doesn't have 160 MHz support,
but we errorneously assumed the opposite. If the flag was set, we
were considering that 160 MHz was supported, but it's actually the
opposite. Fix it by inverting the bits, i.e. NO_160 is 0x1 and 160
is 0x0.

This commit updates the BMPS exit path to be consistent with downstream in
terms of exiting BMPS mode. Downstream sets the flag to send a NULL data
frame to the host on exiting BMPS.
This will tell the AP to send any queued frames to the STA immediately.
Verified the relevant bit toggle in wireshark.

qmi_msg_handler[] and ath10k_qmi_ops are only used as input arguments
to qmi_handle_init() which accepts const pointers to both qmi_ops and
qmi_msg_handler. Make them const to allow the compiler to put them in
read-only memory.

Should an error occur after calling 'ath10k_usb_create()', it should be
undone by a corresponding 'ath10k_usb_destroy()' call

If 'ath10k_usb_create()' fails, we should release some resources and report
an error instead of silently continuing.
