pfSense

Several DSCP choices are non-functional in pfSense 2.2 rules and when chosen, they result in a broken ruleset that will not load. The same list was available in pfSense 2.1.x and had been working, so users that had certain DSCP choices active on 2.1.x may have a broken ruleset post-upgrade.

I tested all of the available DSCP choices and below are the results. The first text is the GUI choice, if there is an item in parenthesis afterwards, that is the value that is put into the ruleset, not the same as the GUI choice.

af11 - OK
af12 - OK
af13 - OK
af21 - OK
af22 - OK
af23 - OK
af31 - OK
af32 - OK
af33 - OK
af41 - OK
af42 - OK
af43 - OK
VA (44) - Fail -- Works if you use "VA" bare in the ruleset, not 44.
EF - OK
cs1 (8) - Fail
cs2 (16) - Fail
cs3 (24) - Fail
cs4 (32) - Fail
cs5 (40) - Fail
cs6 (48) - Fail
cs7 (56) - Fail
0x01 - OK
0x02 - OK
0x04 - OK

In particular, none of the class selector (CS) choices work.
