These are all changes coming from pending muvm experiments where I'm
trying to speed up and simplify the networking setup in the guest.
v3: In 1/3, set 'slen' for options we won't send to -1 in dhcp_init(),
and reset it for option 80 every time we handle a DHCP request. Add
a comment about DHCP needing a valid message type (option 53)
v2: In 3/3, add in4addr_broadcast to ip.h, instead of open-coding it in
dhcp()
Stefano Brivio (3):
dhcp: Use -1 as "missing option" length instead of 0
dhcp: Introduce support for Rapid Commit (option 80, RFC 4039)
dhcp: Honour broadcast flag (RFC 2131, 4.1)
