Wireshark · Wireshark-dev: Re: [Wireshark-dev] bytes

[<jaiswal.vikash@xxxxxxxxx>]

While trying to write a protocol dissector for a pseudo protocol , I
used this and it did work.
The packet (generated manually using text2pcap) had data in hex , and
the field value in the display was also getting displayed in hex . So I
did not do any special formatting for it .I think due to the FT_BYTES,
the data is simply displayed as hex.
