What: /sys/class/net/<iface>/peak_usb/can_channel_id
Date: November 2022
KernelVersion: 6.2

Description:
PEAK PCAN-USB devices support user-configurable CAN channel
identifiers. Contrary to a USB serial number, these identifiers
are writable and can be set per CAN interface. This means that
if a USB device exports multiple CAN interfaces, each of them
can be assigned a unique channel ID.
This attribute provides read-only access to the currently
configured value of the channel identifier. Depending on the
device type, the identifier has a length of 8 or 32 bit. The
value read from this attribute is always an 8 digit 32 bit
hexadecimal value in big endian format. If the device only
supports an 8 bit identifier, the upper 24 bit of the value are
set to zero.
