Comment:

 > Note: I don't throw exceptions when things like pack() fail because we
 spoke with Stephen that we would change those functions to void and throw
 exceptions with another ticket. I simply added @todo statements there.
 The ticket is #2264

 Reviewed commit 02dd6ed0dd458e7627e06bcab6a5168354e929d6

 I've made (and pushed) minor changes to some text in the following files:
 * src/bin/dhcp4/dhcp4_messages.mes
 * src/bin/dhcp6/dhcp6_messages.mes
 * src/lib/dhcp/iface_mgr.cc

 Other comments:

 '''src/lib/dhcp/tests/iface_mgr_unittest.cc'''[[BR]]
 Test socketsFromRemoteAddress: suggest moving the call to
 ifaceMgr->closeSockets() to the end of the function (after the #endif for
 OS_LINUX).  That way, if running the test on Linux, socket3 will be closed
 on exit as well.

 '''tests/tools/perfdhcp/test_control.cc'''[[BR]]
 receivePackets(): messages written to cout should probably be written to
 cerr (as they are error messages).

 Unless you alter something else, I don't need to see the corrections.
 Please merge after you've made (and tested) then.
