Not necessarily; the following item from the Ethereal FAQ discusses
this:
http://www.ethereal.com/faq.html#q4.22
I don't know what OSes, or what drivers in those OSes, will supply bad
packets, such as packets with bad CRCs, to the capture mechanism used by
libpcap (except that, in at least some versions of FreeBSD, the driver
for the Intel EtherExpress Pro 100+, or whatever the "fxp" interface is
called, will do so in promiscuous mode - but will *NOT* supply any
indication of whether the packet was bad or not).

Not unless the OS packet capture mechanism, and the driver, supplies the
CRC field. The FreeBSD driver I mentioned above does *NOT* do so (it
doesn't put the network interface into such a mode).
