- reg : Contains two fields. The first one describes the

INPUT_PROP_ACCELEROMETER

Directional axes on this device (absolute and/or relative x, y, z) represent
accelerometer data. All other axes retain their meaning. A device must not mix
regular directional axes and accelerometer axes on the same event node.

The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
4.1.6 RAW socket returned message flags
4.1.6 RAW socket option CAN_RAW_JOIN_FILTERS
The CAN_RAW socket can set multiple CAN identifier specific filters that
lead to multiple filters in the af_can.c filter processing. These filters
are indenpendent from each other which leads to logical OR'ed filters when
applied (see 4.1.1).
This socket option joines the given CAN filters in the way that only CAN
frames are passed to user space that matched *all* given CAN filters. The
semantic for the applied filters is therefore changed to a logical AND.
This is useful especially when the filterset is a combination of filters
where the CAN_INV_FILTER flag is set in order to notch single CAN IDs or
CAN ID ranges from the incoming traffic.
4.1.7 RAW socket returned message flags
When using recvmsg() call, the msg->msg_flags may contain following flags:
