Hello,

I have written a custom dissector plugin for internal use and am using
"WTAP_ENCAP_USER0" as port. In my dissector, I am setting protocol name and
info field using col_set_str function.

But it still shows the entry set in packet-frame.c. The protocol field is
displayed as UNKNOWN and info field as WTAP_ENCAP = 45. If I comment out
this line in packet-frame.c, then I can see the information and protocol
that I set.

How can make my col_set_str to take effect and display my protocol and info
instead.

Thanks,

Rashmi.
