The following patch series adds Dynamic Host Configuration Protocol
(DHCP) over InfiniBand per IETF standard RFC 4390.

The two main complexities with this are:
1. IPoIB client hardware address is 20 bytes so it doesn't fit into
client hardware address (limited to 16 bytes) so DHCP client identifier
is used.
2. The client must set the BROADCAST flag in both DHCPDISCOVER and
DHCPREQUEST messages to ensure that the server broadcasts it's reply to
the client.

Note these changes are for Linux (LPF) and are against the 4.2.1-P1
version of DHCP.
