By default udhcpc asks for a default list of options; the config option
defaultreqopts allows to tweak this behavior.
When set to 0 udhcpc will not ask for any options except for the options
specified in the reqopts config option.

udhcpc doesn't send a hostname by default. Use the system hostname if
nothing else is specified, to always send a hostname.
It syncs the behaviour to odhcpc, which always sends a hostname.

This option, defined by RFC3442, allows a DHCP server to send static
routes to a client. But the client has to request this option
explicitely.
Static routes are useful when the gateway configured by DHCP cannot be
in the same subnet as the client. This happens, for instance, when
using DHCP to hand out addresses in /32 subnets.
A new configuration option "classlessroute" is available, allowing
users to disable this feature (the option defaults to true).
Other DHCP clients already request this option by default (dhcpcd, for
instance, and possibly Windows). If a DHCP server does not support
this option, it will simply ignore it.

Passing the hostname is currently broken in since the shipped busybox includes this commit:

Remove the udhcpc -R release option as sending a DHCP release
is configurable via the uci option release.

Make sending a DHCP release configurable when the client exits allowing to clean up
IP/mac state info in intermediate devices.
Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
Let DHCP client send a release when it exists so the DHCP server is
informed the IP address is released and allowing to clean up IP/mac
state info in intermediate devices.

Patch allows to configure the mtu of the dynamic 6rd tunnel interface when created by dhcp script.
In some setups it's desirable to have config control over the 6rd tunnel mtu to maximize the traffic throughput
