Comment:

 There is a bug on OpenBSD which causes sendmsg to fail if CMSG_LEN is used
 to calculate the message length. The current workaround for this is to use
 CMSG_SPACE which includes message padding and works fine on OpenBSD and
 other OSes.

 Proposed !ChangeLog:
 {{{
 XXX.    [bug]           marcin
         libdhcp++: Used the CMSG_SPACE instead of CMSG_LEN macro to
 calculate
         msg_controllen field of the DHCPv6 message. Use of CMSG_LEN causes
         sendmsg failures on OpenBSD due to a bug on OpenBSD.
         (Trac #1824, git aabc)

 }}}
