FCS stands for frame check sequence. If the FCS doesn't match the constant in the code, the frame is corrupt. It's true that if you disable the FCS check that you "receive" more frames. You will also see the corrupt ones.

(If you wonder why the FCS compares against a constant, you should have a look at the standard.)
