Other protocol handlers, like uqmi, are also able to setup the MTU,<br>
and instead of doing it via proto_send_update, they just do it like<br>
this:<br>
<br>
[ -n "$mtu" ] && {<br>
echo "Setting MTU to $mtu"<br>
/sbin/ip link set dev $ifname mtu $mtu<br>
}<br>
<br>
I guess we can do the same in the ModemManager protocol handler.<br>
