In the past we had multiple instances where RIFs were not properly
deleted.
One of the reasons for leaking a RIF was that at the time when IP
addresses were flushed from the respective netdev (prompting the
destruction of the RIF), the netdev was no longer a mlxsw upper. This
caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN
event and leak the RIF.
Instead of checking whether the netdev is our upper when an IP address
is removed, we can instead check if the netdev has a RIF configured.
To look up a RIF we need to access mlxsw private data, so the patch
stores the notification blocks inside a mlxsw struct. This then allows
us to use container_of() and extract the required private data.

Next patch is going to make RIF deletion more robust by removing
reliance on fragile mlxsw_sp_lower_get(). This is because a netdev is
not necessarily our upper anymore when its IP addresses are flushed.
The inet{,6}addr notification blocks are going to resolve 'struct
mlxsw_sp' using container_of(), but the functions they call still use
mlxsw_sp_lower_get().
As a preparation for the next patch, propagate 'struct mlxsw_sp' down to
the functions called from the notification blocks and remove reliance on
mlxsw_sp_lower_get().

When a LAG device or a VLAN device on top of it is enslaved to a bridge,
the driver propagates the CHANGEUPPER event to the LAG's slaves.
This causes each physical port to increase the reference count of the
internal representation of the bridge port by calling
mlxsw_sp_port_bridge_join().
However, when a port is removed from a LAG, the corresponding leave()
function is not called and the reference count is not decremented. This
leads to ugly hacks such as mlxsw_sp_bridge_port_should_destroy() that
try to understand if the bridge port should be destroyed even when its
reference count is not 0.
Instead, make sure that when a port is unlinked from a LAG it would see
the same events as if the LAG (or its uppers) were unlinked from a
bridge.
The above is achieved by walking the LAG's uppers when a port is
unlinked and calling mlxsw_sp_port_bridge_leave() for each upper that is
enslaved to a bridge.

Commit b3529af6bb ("spectrum: Reference count VLAN entries") started
reference counting port-VLAN entries in a similar fashion to the 8021q
driver.
However, this is not actually needed and only complicates things.
Instead, the driver should forbid the creation of a VLAN on a port if
this VLAN already exists. This would also solve the issue fixed by the
mentioned commit.
Therefore, remove the get()/put() API and use create()/destroy()
instead.
One place that needs special attention is VLAN addition in a VLAN-aware
bridge via switchdev operations. In case the VLAN flags (e.g., 'pvid')
are toggled, then the VLAN entry already exists. To prevent the driver
from wrongly returning EEXIST, the driver is changed to check in the
prepare phase whether the entry already exists and only returns an error
in case it is not associated with the correct bridge port.

In commit 993107fea5 ("mlxsw: spectrum_switchdev: Fix VLAN device
deletion via ioctl") I fixed a bug caused by the fact that the driver
views differently the deletion of a VLAN device when it is deleted via
an ioctl and netlink.
Instead of relying on a specific order of events (device being
unregistered vs. VLAN filter being updated), simply make sure that the
driver performs the necessary cleanup when the VLAN device is unlinked,
which always happens before the other two events.

Currently, when a RIF is constructed on top of a FID, the RIF increments
the FID's reference count and the RIF is destroyed when the FID's
reference count drops to 1. This effectively means that when no local
ports are member in the FID, the FID is destroyed regardless if the
router port is a member in the FID or not.
The above can lead to the unexpected behavior in which routes using a
VLAN interface as their nexthop device are no longer offloaded after the
last local port leaves the corresponding VLAN (FID).
Example:
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload
# bridge vlan del vid 10 dev swp3
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1
After the patch, the route is offloaded before and after the VLAN is
removed from local port 'swp3', as the RIF corresponding to 'br0.10'
continues to exists.
In order to remove RIFs' reliance on the underlying FID's reference
count, we need to add a reference count to sub-port RIFs, which are RIFs
that correspond to physical ports and their uppers (e.g., LAG devices).
In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to
hold a reference on the RIF. For example:
bond0.10
|
bond0
|
+-------+
| |
swp1 swp2
Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the
RIF corresponding to 'bond0.10'. When the last reference is dropped, the
RIF will be destroyed.

The Broadcom controller on aries S5PV210 boards sends out a couple of
unknown packets after the firmware is loaded. This will cause
logging of errors such as:
Bluetooth: hci0: Frame reassembly failed (-84)
This is probably also the case with other boards, as there are related
Android userspace patches for custom ROMs such as
https://review.lineageos.org/#/c/LineageOS/android_system_bt/+/142721/
Since this appears to be intended behaviour, treated them as diagnostic
packets.

On many devices the RTL8723BS device gets reset during suspend/resume,
causing it to lose its firmware and all state.
Testing has shown it drops back to communicating at 115200 bps and sends
sync-request packages, indicating it has been fully reset.
This commit fixes this by queueing a reprobe on resume.
This mirrors how USB RTL BT devices, which have the same problem, are
handled in the btusb driver, there we set the USB_QUIRK_RESET_RESUME for
all RTL devices, which also causes a reprobe on resume. The only difference
is that here we need to do the reprobe ourselves.
Since we are doing a full reprobe on resume now, we can also turn off the
device on suspend to save power while suspended.

The datasheets for BCM20702 and BCM43438 both have power up time
sequence graphs, however they are slightly different. Both chips
also have an internal power-on-reset, which holds the chip in reset
for a short time after the regulators are enabled.
For the BCM20702, the time period from when the regulators are enabled,
until the chip settles and comes out of sleep state, is 6564 ~ 8171 us.
For the BCM43438, the graph only shows the time period from when the
regulators are enabled until the chip responds by driving the host's
CTS line low, assuming the host has already driven its RTS line low.
This is shown to be 6.5 sleep cycles, with the sleep clock at 32.768
kHz. This is around 2 ms.
Wait a full 10 ms after the regulators are enabled to account for signal
