            Description

            During my work on PSEIP-255, PSLWIP-357 and PSEISV5-197, I discovered the following issue with the DHCP implementation on the release branch, which I have fixed along the way for trunk.

            When a domain name is retrieved via DHCP which has odd number of characters, the stack applies wrong padding of domainname in attribute 5 of TCP/ Interface object.

            The terminating NUL-byte is set at the wrong index in the string.
