This is done by using recvmsg() instead of recvfrom() to allow the timestamp

When the application (here 'candump') ist not fast enough to process the
incomming CAN frames the frames are dropped in the socket receive queue.
When this happens and '-d' is set, we get this info now:

can-utils: canfdtest, a full duplex test to find out-of-order messages
This patch is a pepped up version of Valdislav's canecho_gen and
canecho_dut test programs, which have prooved to be useful for
detecting out-of-order message transmisson and reception. Here
is a list of the changes and improvements:
- Both programs have been merged into on test program named
canfdtest. Message generation can be selected via the command
line option '-g'.
- The test loop count can be specified.
- A low and high verbosity level has been added.
- send/recv is used instead of write/read.
- The return code of send/recv is checked properly.
- Use Linux coding style.

Fix sloppy CAN_(EFF|RTR)_FLAG handling in can_filter.can_mask .
Due to a wrong safety check in af_can.c it was not possible to filter
for SFF frames with a specific CAN identifier without getting the
same selected CAN identifier from a received EFF frame also.
This fix has a minimum impact on the CAN filter API as the 'sloppy'
handling is still a correct (and possibly wanted?) use-case.
Please update the can-utils (especially candump) whose filter definition
on the commandline made assumptions to correct the user input that are
probably unwanted now.
