[PATCH v3 0/3] dhcp: Add support for Rapid Commit, broadcast replies

[Stefano Brivio <sbrivio@redhat.com>]

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)
