Description of problem:
dhcp6s fails to start on systems with 802.1Q VLAN network interface. It expects
the names of network interfaces are something like eth0, eth1 and so. It fails
in case of 802.1Q interface names like eth0.256 or eth1.44


Version-Release number of selected component (if applicable):
dhcpv6-0.10-42.fc7

How reproducible:

Steps to Reproduce:
1.
Enable 802.1Q support
# grep VLAN /etc/sysconfig/network
VLAN=yes

2.
Create interface
# more /etc/sysconfig/network-scripts/ifcfg-eth1.44
DEVICE=eth1.44
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
IPV6INIT=yes

3.
Edit /etc/dhcp6s.conf and /etc/server6_addr.conf to use name of interface eth1.44

4.
Start dhcp6s
# service dhcp6s start

  
Actual results:
dhcp6s[5458]: syntax error in line 1: eth1.44
dhcp6s[5458]: fatal parse failure: exiting in line 1: eth1.44
dhcp6s[5458]: failed to parse addr configuration file

Expected results:
ps ax |grep dhcp6
 5512 ?        Ss     0:00 /usr/sbin/dhcp6s -c /etc/dhcp6s.conf eth1.44
 5529 pts/3    R+     0:00 grep dhcp6

This bug was reported a year ago to upstream developers, but these @#$%^ ignores it.
