tuxera: split AC87U version from other ARM routers, as newer modules fail to load on these, and make these use the older 3014.7.7.1 build
webui: allow 6 digits to be entered in the conntrack TCP timeout Estabglished field, since ARM defaults to a 6-digit value
rc: when disabling IPv6 at build time some IPv6-related code was still being included
webui: preserve (or insert if creating a new reservation) device name on the DHCP reservation list when editing the network client list
