altq pf and interface group

[holger glaess <hglaess_(_at_)_web_(_dot_)_de>]

hi
i try to use an interface group name together with altq in my firewall config .

example 
ifconfig bge0 group wan_if



altq on wan_if cbq bandwidth 100Mb queue { std, www, ssh, admin  }

if i try to aktivate  this i got an syntax error from pfctl.

if i do the interface as macro and the altq line like this

altq on $wan_if cbq bandwidth 100Mb queue { std, www, ssh, admin  }
everything works perfekt.

all other kinds rules works perfect with the interface group name
( rules , rdr , nat )

it is an bug ?
