Wouldn't that be the same anyways when having either the string '0x10'
or the string 'Minimize-Delay' (which is equal to 0x10 as shown in
tcrules) ? I'm afraid I don't see the nuance in there. I'd
appreciate if you can detail how it works.

Thanks. Although I only get the following output for the only device
under TC:
% shorewall show filters
Device fe-4-2:
filter parent 1: protocol all pref 276 fw
filter parent 1: protocol all pref 276 fw handle 0x1 classid 1:11
filter parent 1: protocol all pref 276 fw handle 0x2 classid 1:12
Whereas the tc command would confirm that TC is applied:
% tc -s -d class show dev fe-4-2
class htb 1:11 parent 1:1 leaf 2: prio 1 quantum 2500 rate 7500Kbit
ceil 67500Kbit burst 2535b/8 mpu 0b overhead
