If userspace doesn't properly separate the bitstream input into
individual frames (which may happen for example on slightly
corrupted streams) the CODA hardware may decode more frames
than we expect. We already log an error in this case, but it's
also necessary to adjust the sequence offset. Otherwise we
spam the log with a sequence number mismatch on every frame
frame after the unexpected one.

The MFC driver has two controls, DISPLAY_DELAY and DISPLAY_DELAY_ENABLE
that allow forcing the decoder to return a decoded frame sooner
regardless of the order. The added support for firmware version 6 and
higher was not taking into account the DISPLAY_DELAY_ENABLE boolean.
Instead it had a comment stating that DISPLAY_DELAY should be set to a
negative value to disable it. This is not possible since the control
range is from 0 to 65535. This feature was also supposed to be disabled
by default in order to produce frames in display order.

8250 earlycon is broken on multi-platform ARC because the UART clk
value (BASE_BAUD) is fixed at build time.
Instead, determine the appropriate UART clk at runtime; parse the
devicetree early for platforms requiring alternate UART clk values
(currently only the TB10X platform).

====================
switchdev offload flags
This patch series introduces new offload flags for switchdev.
Kernel network subsystems can use this flag to accelerate
network functions by offloading to hw.
I expect that there will be need for subsystem specific feature
flag in the future.
This patch series currently only addresses bridge driver link
attribute offloads to hardware.
Looking at the current state of bridge l2 offload in the kernel,
- flag 'self' is the way to directly manage the bridge device in hw via
the ndo_bridge_setlink/ndo_bridge_getlink calls
- flag 'master' is always used to manage the in kernel bridge devices
via the same ndo_bridge_setlink/ndo_bridge_getlink calls
Today these are used separately. The nic offloads use hwmode "vepa/veb" to go
directly to hw with the "self" flag.
At this point i am trying not to introduce any new user facing flags/attributes.
In the model where we want the kernel bridging to be accelerated with
hardware, we very much want the bridge driver to be involved.
In this proposal,
- The offload flag/bit helps switch asic drivers to indicate that they
accelerate the kernel networking objects/functions
- The user does not have to specify a new flag to do so. A bridge created with
switch asic ports will be accelerated if the switch driver supports it.
- The user can continue to directly manage l2 in nics (ixgbe) using the
existing hwmode/self flags
- It also does not stop users from using the 'self' flag to talk to the
switch asic driver directly
- Involving the bridge driver makes sure the add/del notifications to user
space go out after both kernel and hardware are programmed
(To selectively offload bridge port attributes,
example learning in hw only etc, we can introduce offload bits for
per bridge port flag attribute as in my previous patch
https://patchwork.ozlabs.org/patch/413211/. I have not included that in this
series)
v2
- try a different name for the offload flag/bit
- tries to solve the stacked netdev case by traversing the lowerdev
list to reach the switch port
v3 -
- Tested with bond as bridge port for the stacked device case.
Includes a bond_fix_features change to not ignore the
NETIF_F_HW_NETFUNC_OFFLOAD flag
- Some checkpatch fixes
v4 -
- rename flag to NETIF_F_HW_SWITCH_OFFLOAD
- add ndo_bridge_setlink/dellink handlers in bond and team drivers as
suggested by jiri.
- introduce default ndo_dflt_netdev_switch_port_bridge_setlink/dellink
handlers that masters can use to call offload api on lowerdevs.

ndo_bridge_setlink/dellink handlers
We want bond to pick up the offload flag if any of its slaves have it.
NETIF_F_HW_SWITCH_OFFLOAD flag is added to the mask, so that
netdev_increment_features does not ignore it.
This also adds ndo_bridge_setlink and ndo_bridge_dellink handlers.
These currently point to the default handlers provided by the
switchdev api.

This patch adds support to set/del bridge port attributes in hardware from
the bridge driver.
With this, when the user sends a bridge setlink message with no flags or
master flags set,
- the bridge driver ndo_bridge_setlink handler sets settings in the kernel
- calls the swicthdev api to propagate the attrs to the switchdev
hardware
You can still use the self flag to go to the switch hw or switch port
driver directly.
With this, it also makes sure a notification goes out only after the
attributes are set both in the kernel and hw.
The patch calls switchdev api only if BRIDGE_FLAGS_SELF is not set.
This is because the offload cases with BRIDGE_FLAGS_SELF are handled in
the caller (in rtnetlink.c).

This patch adds two new api's netdev_switch_port_bridge_setlink
and netdev_switch_port_bridge_dellink to offload bridge port attributes
to switch port
(The names of the apis look odd with 'switch_port_bridge',
but am more inclined to change the prefix of the api to something else.
Will take any suggestions).
The api's look at the NETIF_F_HW_SWITCH_OFFLOAD feature flag to
pass bridge port attributes to the port device.

This is a high level feature flag for all switch asic offloads
