conf.apf documentation problem for IFACE_TRUSTED

[interworx]

The conf.apf says:

Trusted Network interface(s); all traffic on defined interface(s) will by-pass

ALL firewall rules, format is white space or comma separated list.

IFACE_TRUSTED=""

It appears that comma separated is not actually supported however. There's no error, but it just doesn't work.

files/firewall does: if [ ! "$IFACE_TRUSTED" == "" ]; then for i in echo $IFACE_TRUSTED; do

which doesn't take comma separated into account, and I don't see any place else that tries to.
