Closes-Bug: 1717236
This is an updated version of c377f5cbbd
which problems with PXE and dnsmasq due to buggy dnsmasq code which uses
siaddr field to specify tftp server. They are addressed now by always
sending server-ip-address to make sure that dnsmasq works.
More information about siaddr and option 150,66 can be found in
informational RFC https://tools.ietf.org/html/rfc5859
