For 8852CE, there is abnormal state called CMDPSR_FRZTO,
which occasionally happens in some platforms, and could be
found by firmware and fixed in current SER flow, so we add
suppress function to avoid verbose message for this resolved case.

Newer FW re-design SER (syetem error recovery) L1 (level 1) flow.
New L1 flow will expect two extra states before original L1 flow.
* Before:
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver
* After:
fw --- pre-M0 --> driver
fw <-- post-M0 --- driver
fw --- M1 --> driver
fw <-- M2 --- driver
fw --- M3 --> driver
fw <-- M4 --- driver
fw --- M5 --> driver
Then before M1, FW gets one more interval to deal with things that FW
should have handled well. To consider backward/forward compatibility,
FW and driver won't change flow from M1 to M5. (only except that halt
trigger control will change a little bit.) So, there will be two differnt
starting points of SER L1.
* old FW: SER L1 starts from M1
* new FW: SER L1 starts from pre-M0
Then, driver adds the new SER L1 entry and also keep the original one
instead of changing it.

RTL8851B keeps almost the same interrupt flow as RTL8852A and RTL8852B.
But, it uses a different bitmask for interrupt indicator of FW HALT C2H.
So, we make a chip judgement in pci when configuring interrupt mask.

U-NII-4 band, i.e 5.9GHz channels, can be supported by chip 8852C, 8852B
and 8851B. But, it is not supported by chip 8852A. Flag support_unii4 is
added in chip info and defined by chip accordingly to indicate that.
We reference this flag of runtime chip to decide whether to register
5.9GHz channels.
After that, we consider if U-NII-4 band is allowed by our regulatory
rule of U-NII-4. If chip::support_unii4 but not regd::allow_unii4,
we stll do not register 5.9GHz channels.

For realtek regulatory, there are following two kinds of configurations
to determine whether to allow UNII-4 band, i.e. 5.9GHz channels.
1. default setting according to whether chip support it or not
2. evaluate realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_59G_EN (func. 6)
If (1) is false, we won't try (2) and just disallow UNII-4. Otherwise,
if (2) is not supported or returns a non-specific value, we follow the
default setting either. Besides, this commit aims to add decision logic
in rtw89 regulatory. Actually, driver doesn't register UNII-4 yet. That
will be handled by another commit.

The type of "mwifiex_adapter->nd_info" is "struct cfg80211_wowlan_nd_info",
not "struct cfg80211_wowlan_nd_match".
Use struct_size() to ease the computation of the needed size.
The current code over-allocates some memory, so is safe.
But it wastes 32 bytes.

Now that we no longer need to check whether the DMA address is within
the TSO header DMA memory range for the queue, we can allocate the TSO
header DMA memory in chunks rather than one contiguous order-6 chunk,
which can stress the kernel's memory subsystems to allocate.
Instead, use order-1 (8k) allocations, which will result in 32 order-1
pages containing 32 TSO headers.

Now that we use a different buffer type for TSO headers, we can use
buf->type to determine whether the original buffer was DMA-mapped or
not. The rules are:
MVNETA_TYPE_XDP_TX - from a DMA pool, no unmap is required
MVNETA_TYPE_XDP_NDO - dma_map_single()'d
MVNETA_TYPE_SKB - normal skbuff, dma_map_single()'d
MVNETA_TYPE_TSO - from the TSO buffer area
This means we only need to call dma_unmap_single() on the XDP_NDO and
SKB types of buffer, and we no longer need the private IS_TSO_HEADER()
which relies on the TSO region being contiguously allocated.

The transmit code assumes that the transmit descriptors that are used
begin with the first descriptor in the ring, but this may not be the
case. Fix this by providing a new function that dma-unmaps a range of
numbered descriptor entries, and use that to do the unmapping.

Now macsec on top of vlan can be offloaded to macsec offloading
devices so that VLAN tag is sent in clear text on wire i.e,
packet structure is DMAC|SMAC|VLAN|SECTAG. Offloading devices can
simply enable NETIF_F_HW_MACSEC feature in netdev->vlan_features for
this to work. But the logic in offloading drivers to retrieve the
private structure from netdev needs to be changed to check whether
the netdev received is real device or a vlan device and get private
structure accordingly. This patch changes the offloading drivers to
use helper macsec_netdev_priv instead of netdev_priv.

If skb enqueue the qdisc, fq_skb_cb(skb)->time_to_send is changed which
is actually skb->cb, and IPCB(skb_in)->opt will be used in
__ip_options_echo. It is possible that memcpy is out of bounds and lead
to stack overflow.
We should clear skb->cb before ip_local_out or ip6_local_out.
v2:
1. clean the stack info
2. use IPCB/IP6CB instead of skb->cb

Before blamed commit, pskb_may_pull() was used instead
of skb_header_pointer() in __vlan_get_protocol() and friends.
Few callers depended on skb->head being populated with MAC header,
syzbot caught one of them (skb_mac_gso_segment())
Add vlan_get_protocol_and_depth() to make the intent clearer
and use it where sensible.
This is a more generic fix than commit e9d3f80935b6
("net/af_packet: make sure to pull mac header") which was
dealing with a similar issue.

Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3ce9
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.
ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000
To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove

The remove callback is only ever called after .probe() returned
successfully. After that get_stmmac_bsp_priv() always return non-NULL.
Side note: The early exit would also be a bug because the return value
of qcom_ethqos_remove() is ignored by the device core and the device is
unbound unconditionally. So exiting early resulted in a dangerous
resource leak as all devm allocated resources (some memory and the
register mappings) are freed but the network device stays around. Using
the network device afterwards probably oopses.
