Isn't it that we only have to take special care of the andX
type requests? For the other ones we should not even notice
that there are multiple requests in a TCP packet. 0x2f is
writeX, this might require special handling, but the fact
that 0x32 (trans2) is followed by something else in the same
frame shouldn't be noticed by smbd at all.

Or are you doing something special magic to wrap these into
the same netbios-level message (no idea how this should
work...)? :-)
