Ethereal can provide only what the operating system code it uses can
provide; if your OS's raw packet capture mechanism, and the driver for
your networking card, and your networking card itself can be configured
to supply packets that had CRC errors (and, presumably, supply a flag
indicating whether the packet had a CRC error), then it would probably
be possible to modify the libpcap library (that's the library Ethereal
uses as a platform-independent interface to the OS's raw packet capture
mechanism) to do that configuration, if it's possible to do so from a
program, and then to modify Ethereal (or any other program that uses
libpcap) to handle that.
