Get rid of the code that attempts to deal with the FCS; if the
link-layer dissector hasn't removed the FCS, either:
1) the link-layer dissector is buggy and should be fixed;
or
2) the link-layer dissector doesn't know whether there's an FCS
and you have to tell it by setting a preference (and if there
is no such preference, one needs to be added).
The code in question was causing errors when the link-layer dissector
was removing the FCS when it's known to be present, as it should do.
Get rid of 4-space tabs in favor of spaces.
