After a few complaint about 100% CPU usage of canfdtest over our PCI
-like boards, I have had a look to the source file, and think I have
found the issue in can_echo_dut().

replaced strcpy(if_name, argv[x]) + ioctl by if_idx = if_nametoindex(argv[x])

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.
