For isolating slirp-attached guests from the world, QEMU provides the restricted mode. However, its implementation suffers from bugs that makes it practically unusable. Most probablematic is broken DHCP.
This series fixes that and canonicalizes the corresponding command line switch. It also cleans up the addressing of the built-in DHCP and TFTP server and drops the pointless m_freem wrapper. Please review/merge.
