[DHCP] Add support for ProxyDHCP requests
The PXE spec is (as usual) unclear on precisely when ProxyDHCPREQUESTs
should be issued. We adapt the following, slightly paranoid approach:
If an offer contains an IP address, then it is a normal DHCPOFFER.
If an offer contains an option #60 "PXEClient", then it is a
ProxyDHCPOFFER. Note that the same packet can be both a normal
DHCPOFFER and a ProxyDHCPOFFER.
After receiving the normal DHCPACK, if we have received a
ProxyDHCPOFFER, we unicast a ProxyDHCPREQUEST back to the ProxyDHCP
server on port 4011. If we time out waiting for a ProxyDHCPACK, we
treat this as a non-fatal error.
