As far as I know, the vDSO specs (both Documentation/ABI/stable/vdso and

This patch series adds a new SoundWire subsystem which implements a
new MIPI bus protocol 'SoundWire'.
The SoundWire protocol is a robust, scalable, low complexity, low
power, low latency, two-pin (clock and data) multi-drop bus that
allows for the transfer of multiple audio streams and embedded

SoundWire bus provides sdw_read() and sdw_write() APIs for Slave
devices to program the registers. Provide support in regmap for

Set up the HW switch to trap IGMP packets to CPU port.

IGMP packets should be trapped to the CPU port. The SW bridge knows
whether to forward to other ports.
With "IGMP snooping for local traffic" merged, IGMP trapping is also
required for stable IGMPv2 operation.
LAN9303 does not trap IGMP packets by default.
Enable IGMP trapping in lan9303_setup.
Now that IGMP packets no longer is flooded in HW, we want the SW bridge to
forward packets based on bridge configuration. To make that happen,
IGMP packets must have skb->offload_fwd_mark = 0.
