If the driver reset fails, it may not work properly.
Therefore, the ndo.open() operation should be rejected.
In this patch, the driver calls netif_device_detach()
before the reset and calls netif_device_attach()
after the reset succeeds. If the reset fails,
netif_device_attach() is not called. Therefore,
netdev does not present and cannot be opened.
If reset fails, only the PCI reset (via sysfs)
can be used to attempt recovery.

When the user dumps statistics, the hibmcge driver automatically
updates all statistics. If the driver is performing the reset operation,
the error data of 0xFFFFFFFF is updated.
Therefore, if the driver is resetting, the hbg_update_stats_by_info()
needs to return directly.

====================
net: faster and simpler CRC32C computation
Update networking code that computes the CRC32C of packets to just call
crc32c() without unnecessary abstraction layers. The result is faster
and simpler code.
Patches 1-7 add skb_crc32c() and remove the overly-abstracted and
inefficient __skb_checksum().
Patches 8-10 replace skb_copy_and_hash_datagram_iter() with
skb_copy_and_crc32c_datagram_iter(), eliminating the unnecessary use of
the crypto layer. This unblocks the conversion of nvme-tcp to call
crc32c() directly instead of using the crypto layer, which patch 9 does.

Now that the crc32c() library function directly takes advantage of
architecture-specific optimizations and there also now exists a function
skb_copy_and_crc32c_datagram_iter(), it is unnecessary to go through the
crypto_ahash API. Just use those functions. This is much simpler, and
it also improves performance due to eliminating the crypto API overhead.

Since skb_copy_and_hash_datagram_iter() is used only with CRC32C, the
crypto_ahash abstraction provides no value. Add
skb_copy_and_crc32c_datagram_iter() which just calls crc32c() directly.
This is faster and simpler. It also doesn't have the weird dependency
issue where skb_copy_and_hash_datagram_iter() depends on
CONFIG_CRYPTO_HASH=y without that being expressed explicitly in the
kconfig (presumably because it was too heavyweight for NET to select).
The new function is conditional on the hidden boolean symbol NET_CRC32C,
which selects CRC32. So it gets compiled only when something that
actually needs CRC32C packet checksums is enabled, it has no implicit
dependency, and it doesn't depend on the heavyweight crypto layer.

Now that the only remaining caller of __skb_checksum() is
skb_checksum(), fold __skb_checksum() into skb_checksum(). This makes
struct skb_checksum_ops unnecessary, so remove that too and simply do
the "regular" net checksum. It also makes the wrapper functions
csum_partial_ext() and csum_block_add_ext() unnecessary, so remove those
too and just use the underlying functions.

Add skb_crc32c(), which calculates the CRC32C of a sk_buff. It will
replace __skb_checksum(), which unnecessarily supports arbitrary
checksums. Compared to __skb_checksum(), skb_crc32c():
- Uses the correct type for CRC32C values (u32, not __wsum).
- Does not require the caller to provide a skb_checksum_ops struct.
- Is faster because it does not use indirect calls and does not use
the very slow crc32c_combine().
According to commit 2817a336d4d5 ("net: skb_checksum: allow custom
update/combine for walking skb") which added __skb_checksum(), the
original motivation for the abstraction layer was to avoid code
duplication for CRC32C and other checksums in the future. However:
- No additional checksums showed up after CRC32C. __skb_checksum()
is only used with the "regular" net checksum and CRC32C.
- Indirect calls are expensive. Commit 2544af0344ba ("net: avoid
indirect calls in L4 checksum calculation") worked around this
using the INDIRECT_CALL_1 macro. But that only avoided the indirect
call for the net checksum, and at the cost of an extra branch.
- The checksums use different types (__wsum and u32), causing casts
to be needed.
- It made the checksums of fragments be combined (rather than
chained) for both checksums, despite this being highly
counterproductive for CRC32C due to how slow crc32c_combine() is.
This can clearly be seen in commit 4c2f24549644 ("sctp: linearize
early if it's not GSO") which tried to work around this performance
bug. With a dedicated function for each checksum, we can instead
just use the proper strategy for each checksum.
As shown by the following tables, the new function skb_crc32c() is
faster than __skb_checksum(), with the improvement varying greatly from
5% to 2500% depending on the case. The largest improvements come from
fragmented packets, mainly due to eliminating the inefficient
crc32c_combine(). But linear packets are improved too, especially
shorter ones, mainly due to eliminating indirect calls. These
benchmarks were done on AMD Zen 5. On that CPU, Linux uses IBRS instead
of retpoline; an even greater improvement might be seen with retpoline:

Since commit 17ec3e71ba79 ("crypto: lib/Kconfig - Hide arch options from
user"), the CRYPTO_CHACHA20_NEON option is no longer selected by default
due to changes in how crypto library options are exposed and selected.
To restore the previous behavior and ensure CRYPTO_CHACHA20_NEON is
enabled, explicitly select CONFIG_CRYPTO_CHACHA20 in the defconfig. This
pulls in CRYPTO_LIB_CHACHA_INTERNAL and allows CRYPTO_CHACHA20_NEON to be
selected automatically as before.

devm_kasprintf() returns NULL when memory allocation fails. Currently,
aspeed_lpc_enable_snoop() does not check for this case, which results in a
NULL pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue.

Commit 7ed3e88664e3 ("wifi: ath12k: update regulatory rules when connection
established") introduced a call to ath12k_reg_handle_chan_list() upon
connection to update the regulatory domain in cfg80211 based on the power
type received from the AP.
However, this update fails because ah->regd_updated was already set to true
during the earlier regulatory update triggered when the interface was
added.
To resolve this, reset ah->regd_updated before calling
ath12k_reg_handle_chan_list() to ensure the update proceeds correctly.

Commit 4c546023d71a ("wifi: ath12k: update regulatory rules when interface
added"), introduced a call to ath12k_reg_handle_chan_list() during
interface addition to update the regulatory domain based on the interface
type. While this works initially, subsequent updates (e.g., after an
interface delete/re-add cycle) fail because ah->regd_updated is never
reset.
To address this, reset ah->regd_updated before calling
ath12k_reg_handle_chan_list() to allow the update to proceed.
However, this change exposes another issue: a timeout occurs when waiting
for the 11D scan to complete, as seen in the log:
ath12k_pci 0000:05:00.0: failed to receive 11d scan complete: timed out
This happens because during interface down, ar->state_11d is set to
ATH12K_11D_PREPARING, and during interface up, the host waits for
ar->completed_11d_scan even though the scan hasn't started yet.
Fix this by updating the wait condition to check for ATH12K_11D_RUNNING,
which is the only state where a scan complete event is expected.

In the current implementation of ath12k_regd_update(), the ah->regd_updated
flag is used to ensure that the regulatory domain is updated only once per
radio. During MAC registration, this function is called to push the default
regulatory domain to cfg80211. At that point, the hardware state is not on
and hence ah->regd_updated remains false.
However, after commit 4c546023d71a ("wifi: ath12k: update regulatory rules
when interface added"), ath12k_reg_handle_chan_list() is invoked when an
interface is added, which in turn calls ath12k_regd_update(). By this time,
hardware state is on and consecutively ah->regd_updated becomes true.
Later, when the 11D scan completes and a new regulatory domain is received
from the firmware, the host attempts to update cfg80211 again via
ath12k_regd_update(). But since ah->regd_updated is already true, the
update is skipped.
>From the user's perspective, this results in a failure to connect to 6 GHz
APs, as the default regulatory domain (the only one pushed to cfg80211)
does not include 6 GHz support.
To resolve this, reset the ah->regd_updated flag when handling the 11D
regulatory domain update.
