Dear Maintainer,
dhclient does not work when doing DHCPv6 with an interface alias, e.g.
dhclient -6 -v eth0:1
fails. The attached patch is required to fix it.
* When comparing enumerated interface name with cmdline interface name,
the cmdline interface name alias extension must be stripped since all
enumerated interface names have their alias extension stripped.
Without this, DHCPv6 fails for interface aliases. (LP: #1693819)
Thanks for considering the patch.

+Description: Since isc-dhcp strips the interface alias from all
+ interfaces it enumerates, when comparing the cmdline interface
+ name to find the matching enumerated interface, the cmdline name
+ must have its alias stripped also. Without this, DHCPv6 fails
+ when using an interface alias.
