Note the "must" there.

So the current behavior looks like an error, to me.


I suspected that this is the violation of DHCP specs.

Many times I saw how FreeBSD to FreeBSD DHCP handshake is delayed without an apparent reason. I think this bug combined with another one when broadcast UDP packet isn't received when source IP is set is the cause of such DHCP delays.
