Setter method for mtu, mapped from YANG variable /interfaces/interface/subinterfaces/subinterface/ipv6/state/mtu (uint32)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_mtu is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_mtu() directly.

    YANG Description: [adapted from IETF IP model RFC 7277]

The size, in octets, of the largest IPv6 packet that the
interface will send and receive.

The server may restrict the allowed values for this leaf,
depending on the interface's type.

If this leaf is not configured, the operationally used MTU
depends on the interface's type.
