From Dustin D. Trammell:
The FIX protocol dissector uses the 6 byte string "8=FIX." at the beginning of
the data to match the beginning of a FIX version string of the format
"8=FIX.x.x" in order to determine if the data is the FIX protocol or not.
With FIX 5.x and beyond, the beginning of the data will have a version string
of the format "8=FIXT.x.x" to indicate the FIX Transport (FIXT) version.
A simple solution is to update the current FIX dissector to only match the
first 5 bytes of the version string (see attached patch). This will cause a
match for FIX version 4.x and prior (8=FIX.x.x) as well as 5.x and beyond
(8=FIXT.x.x).
