--
The display filter “tcp contains fc” gives the following error message because
we handle “fc” as a protocol instead of hex, like we do for other hex values.
Invalid filter: Protocol (“fc”) cannot appear on right-hand side of
comparison.
This error message is difficult to understand because the display filter “tcp
contains fb” and “tcp contains fd” works as expected.
If a protocol or a field is not supported on right-hand side then we should not
handle the right-hand side as a protocol or field for the “contains” and
“matches” operator. Maybe just as bytes, like when using quotes.
