I have made a patch to the e1000 driver (a similar patch should work
on other drivers) to allow it to be configured to return the entire
ethernet frame, ie the FCS too.  Eventually, if I can convince the kernel
folks, there will be an Ethtool ioctl to turn this on/off and query it.

In the meantime, how hard would it be for someone to add an option to
ethereal to tell it that a particular interface or session's packets
include the FCS as the last 4 bytes?  Please note, I'm using a hacked up
proprietary protocol for my testing, so there is no way Ethereal can know
that the last 4 bytes are checksum....

Thanks,
Ben
