[ECOS] DHCP xid

[Robin Farine]

Hugo,

Thank you for your work on this subject and the patch that resulted.

Ahem, forget this if it's already donethe case but, as Martin Buck
emphasized in his e-mail, when the DHCP client receives a reply, it
should first make sure that the fields 'htype', 'hlen' and 'chaddr'
match its own ESA before accepting the reply since the XID doesn't
suffice to exclude e.g. broadcasted replies destined to other clients.
