client_data.vendorclass, .hostname and .fqdn probably need the same treatment:
just insert them into the list of -x opts, get rid of
if (client_data.vendorclass)
udhcp_add_binary_option(packet, client_data.vendorclass);
if (client_data.hostname)
udhcp_add_binary_option(packet, client_data.hostname);
if (client_data.fqdn)
udhcp_add_binary_option(packet, client_data.fqdn);
function old new delta
udhcp_insert_new_option - 166 +166
perform_release 171 207 +36
perform_d6_release 227 259 +32
udhcpc6_main 2558 2580 +22
