Comment:

 There is a new function which checks if the server identifier in a query
 matches any server identifier used by a server. If it doesn't, the packet
 is discarded.

 Proposed !ChangeLog entry:
 {{{
 XXX.    [bug]           marcin
         b10-dhcp4 discards DHCPv4 messages carrying server identifiers
         which don't match server identifiers used by the server.
         (Trac #3279, git abc)

 }}}
