If the array of bytes is a named field, just make it a field of type
FT_BYTES.

If it's not a named field, and you're putting it into the protocol tree
with "proto_tree_add_text()", use "tvb_bytes_to_str()".

Doing one of those won't put a leading "0x" in there, and will just put
in a "..." after 16 bytes rather than showing ever single byte (16 is
1/2 the value of the #define MAX_BYTE_STR_LEN in epan/strutil.c -
MAX_BYTE_STR_LEN is the number of characters in the display, and each
byte is shown as 2 hex digits - so it could be increased), but it's the
type of thing you're asking for .
