Add Support of DHCP VSS Type 0 where VPN-ID is ASCII
Enhence support of DHCP VSS (Virtual Subnet Selection) to include VSS type 0 where VSS info is a NVT (Network Virtual Terminal) ASCII VPN ID where the ASCII string MUST NOT be terminated with a zero byte. Existing code already support VSS type 1, where VSS information is a RFC 2685 VPN-ID of 7 bytes with 3 bytes OUI and 4 bytes VPN index, and VSS type 255 indicating global VPN. Change-Id: I54edbc447c89a2aacd1cc9fc72bd5ba386037608 Signed-off-by: John Lo <loj@cisco.com>
