I've invistigated that m_head mbuf doesn't have M_VLANTAG when performing 
VLAN_OUTPUT()

next diff for /usr/src/sys/net/if_vlan_var.h make it work:

Actually this is partial backout ru@ commit
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/net/if_vlan_var.h.diff?r1=1.20&r2=1.21&f=h

Since it's not adressed to if_nge itself, so it's possible same problems for 
another interfaces.
